Subject: [PATCH 01/25] perf: optimize sorting with useMemo in translation
 history dialog
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Implement CodeRabbit's suggestion to wrap the sorting logic in useMemo to prevent unnecessary recalculations on every render. This improves performance when dealing with large datasets by only recalculating when sessions or sortConfig change.

Subject: [PATCH 02/25] feat(scan): implement TX022 file count-based progress
 for scan operations

Add real-time progress feedback during file scanning operations showing
current file being processed and total count. Updates every 1 file or
1000ms (whichever comes first) following the "Simple over Easy" design.

- Add scan progress event emission in Rust backend with 1000ms throttling
- Add scan progress state management to Zustand store
- Update all tab components to display scan progress during operations
- Show "Scanning: filename (X files)" instead of generic "Scanning..."

Subject: [PATCH 03/25] fix(scan): improve scan progress visibility and
 accuracy

Improve scan progress reporting to address user feedback about poor visibility:
- Show progress as "X / Y files (Z%)" instead of just "(X files)"
- Count total files before scanning for accurate progress percentage
- Update progress more frequently (every 10 files OR every 200ms)
- Emit progress events when finding relevant files (JAR, SNBT, JSON)
- Apply improvements to all scan types (mods, quests, guidebooks, custom files)

This provides better user feedback during scan operations with clear progress
indication and reduces the time when no progress is shown.

Subject: [PATCH 04/25] fix(scan): add progress updates during file analysis
 phase

Fix the issue where scan progress was only shown during initial file
discovery but not during the time-consuming file analysis phase.

- Add progress updates during JAR analysis in mods-tab.tsx
- Add progress updates during quest file analysis in quests-tab.tsx
- Add progress updates during Patchouli book extraction in guidebooks-tab.tsx
- Add progress updates during custom file processing in custom-files-tab.tsx
- Add resetScanProgress() calls in all finally blocks

This ensures users see continuous progress updates throughout the entire
scan process, not just "Please wait..." during the analysis phase.

Subject: [PATCH 05/25] feat(scan): add small progress bar for scan operations

Add a compact progress bar to complement the text-based progress display
during scan operations. The progress bar shows visual completion percentage
alongside the existing "X / Y files (Z%)" text display.

Features:
- Small, compact progress bar (height: 1.5rem)
- Only shows when both processedCount and totalCount are available
- Centered with max-width for better visual balance
- Maintains the existing text progress display above it
- Consistent with the "Simple over Easy" design philosophy

This provides better visual feedback while keeping the interface clean and uncluttered.

Subject: [PATCH 06/25] fix(scan): improve progress bar layout and alignment

Fix layout issues with the scan progress display:
- Set fixed width (w-80) for progress bar to prevent stretching/shrinking
- Change file name alignment from center to left (text-left)
- Keep progress statistics centered (text-center)
- Remove text-center from main container to allow individual control

This provides consistent visual layout regardless of file name length
and better readability with left-aligned file names.

Subject: [PATCH 07/25] fix(scan): prevent progress container from resizing
 with filename length

Fix the scan progress container from expanding/contracting based on filename length:
- Set fixed width (w-96) for the progress content container
- Add truncate class to filename text to handle overflow
- Keep progress bar at fixed width (w-80) within the container

This ensures consistent layout regardless of filename length and prevents
the progress bar from appearing to stretch or shrink.

Subject: [PATCH 08/25] fix(scan): add immediate progress display when scan
 starts

Fix the delay between clicking scan button and progress display appearing
by initializing scan progress state immediately when scanning begins.

Changes:
- Set initial scan progress state right after setScanning(true)
- Initialize with empty currentFile, 0 processedCount, undefined totalCount
- Set appropriate scanType for each tab (mods, quests, guidebooks, custom-files)
- Apply fix to all tab components consistently

This provides immediate visual feedback that scanning has started, instead of
waiting for the first file to be discovered/processed by the backend.

Subject: [PATCH 09/25] perf(scan): optimize re-scan performance and improve
 feedback

Improve scan button responsiveness especially during re-scans by:
- Move heavy state clearing operations to async setTimeout to avoid blocking UI
- Show "Initializing scan..." message immediately for better user feedback
- Reduce UI blocking during translation targets clearing
- Apply optimizations to all tab components consistently

This reduces the perceived delay when clicking scan button after previous scans
by preventing React re-render blocking during large state updates.

Subject: [PATCH 10/25] perf(scan): improve scan performance with better
 optimizations

Revert problematic async setTimeout and implement more effective optimizations:
- Remove setTimeout that caused additional delay
- Add conditional state updates to avoid unnecessary operations
- Use useCallback to memoize handleScan function
- Import useMemo and useCallback for future optimizations
- Only clear state if it actually has content

This provides immediate response while avoiding unnecessary React re-renders
and state updates during re-scan operations.

Subject: [PATCH 11/25] fix(scan): revert problematic optimizations causing
 delays

Revert useCallback and conditional state updates that were causing delays:
- Remove useCallback with problematic dependencies (onScan changes every render)
- Remove conditional state clearing that adds unnecessary checks
- Return to simple, direct state updates for better performance
- Keep only essential optimization: check translationResults length before clearing

The original implementation was actually faster. The perceived delay was not
from React re-renders but from the actual scan processing time.

Subject: [PATCH 12/25] refactor(scan): simplify scan function following
 "Simple over Easy" philosophy
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Remove unnecessary optimizations and return to straightforward implementation:
- Remove useCallback and complex dependency management
- Remove conditional state clearing (if checks)
- Remove unused imports (useCallback, useMemo)
- Use direct state updates for clarity and simplicity
- Keep only essential functionality

This follows the "EasyよりもSimple" design principle - prefer simple,
understandable code over complex optimizations that don't provide clear benefits.

Subject: [PATCH 13/25] fix(scan): add intermediate progress updates after file
 discovery

Fix the delay between scan start and progress display by adding intermediate
progress updates immediately after file discovery phase:

- Show "Analyzing [file type]..." after file discovery completes
- Display total file count before detailed analysis begins
- Apply to all tab types (mods, quests, guidebooks, custom files)
- Provide immediate visual feedback to users

This addresses the two-phase scan process:
1. File discovery (fast) - now shows immediate progress
2. File analysis (slow) - already had progress updates

Users now see continuous progress feedback throughout the entire scan process.

Subject: [PATCH 14/25] fix(scan): prevent UI blocking during scan button press

Fix the issue where scan button remains in pressed state due to UI blocking:
- Move heavy state clearing operations to requestAnimationFrame
- Allow UI to update with isScanning=true before clearing large datasets
- Extract directory path before clearing to avoid delays
- Prevent synchronous React re-renders from blocking button animations

This ensures the scan button animation and progress display appear immediately
without being blocked by clearing existing translation targets.

Subject: [PATCH 15/25] feat(ui): implement comprehensive animation system for
 better UX

- Add click feedback and hover states to all interactive elements
- Implement smooth transitions for buttons, inputs, and form controls
- Add loading animations with spinners for scan and translate operations
- Enhance dialog and modal animations with backdrop blur
- Add staggered animations for table rows and data loading
- Create consistent animation timing (200-300ms) across components
- Improve loading states with enhanced visual feedback
- Add error display animations for better user awareness

Subject: [PATCH 18/25] feat(scan): implement file count-based progress bars
 for scan operations

Backend Changes:
- Add scan progress event emission in filesystem.rs with file count tracking
- Add translation existence check functions for mods, quests, and guidebooks
- Add read_session_log function for session log retrieval
- Add test features and dev dependencies to Cargo.toml
- Export new command functions in lib.rs

Frontend Changes:
- Implement scan progress UI with progress bars and file count display
- Add scan state management and progress tracking
- Update tab switching to prevent switching during scan operations
- Add loading animations and improved UI feedback
- Update various UI components with progress-related improvements

Features:
- Real-time progress updates during file scanning
- File count-based progress indicators
- Responsive UI with loading states
- Tab locking during scan operations
- Enhanced error handling and user feedback

Subject: [PATCH 19/25] refactor(json): implement sorted JSON serialization for
 consistency

- Replace serde_json::to_string_pretty with serialize_json_sorted in backup.rs
- Update config.rs to use sorted JSON serialization for all config operations
- Add session ID format validation in backup.rs
- Update lang_file_test.rs to test sorted JSON functionality
- Ensure consistent JSON key ordering across all output files
- Improve file diff readability and maintainability

Subject: [PATCH 24/25] fix(ui): constrain maximum widths for better layout
 consistency

- Set main layout container max width to 1600px on 2xl screens
- Add xl breakpoint with max-w-6xl for better responsive scaling
- Limit translation history dialog to 1600px max width on large screens
- Reduce dialog width from 95vw to 90vw for better margins

Subject: [PATCH 25/25] fix(clippy): resolve uninlined_format_args warnings
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Update format strings to use inline arguments to comply with Clippy's
uninlined_format_args lint. This fixes the failing Backend Tests job
in CI by addressing all format\! macro calls that were using the older
"{}", var syntax instead of the newer "{var}" syntax.
