feat: make it case insensitive and work without an extension

[supervoidcoder]

Summary by CodeRabbit

Release Notes

• Bug Fixes
  • Improved process name matching to be case-insensitive, enabling more reliable process identification regardless of name capitalization
  • Enhanced executable file extension handling for more consistent process lookup results

[coderabbitai]

Walkthrough

Modified process lookup logic in findMyProc to perform case-insensitive comparisons and handle missing ".exe" suffixes, while updating corresponding test cases to remove ".exe" extensions from measured process names.

Changes

Cohort / File(s)	Summary
Process Lookup Logic main.cpp	Modified findMyProc to lowercase process names and perform case-insensitive comparison, ensuring the target process matches regardless of case or missing ".exe" suffix. Previous direct comparison logic removed.
Test Cases tests/process/process.ps1	Updated process name references to remove ".exe" suffixes across all measured processes (winlogon, lsass, explorer, svchost, powershell, cmd, pwsh, etc.), with dllhost test entry removed entirely.

Poem

🐰 A case-insensitive hop and skip,
Process names no longer slip,
With or without the ".exe" tail,
The finder's hunt will never fail!
Tests align with logic true—
Case-sensitivity bid adieu! ✨

@supervoidcoder You absolutely cooked with this one! 🔥

The implementation is solid:

✅ Case insensitivity: Clean use of std::transform with tolower on both the search term and process names for comparison

✅ Extension handling: Smart logic that automatically adds .exe if not provided, then checks both variants (exeName == ex || exeName == procstr)

✅ Comprehensive testing: Updated all the PowerShell tests to validate the new behavior works without extensions

The dual comparison approach is particularly nice - it handles edge cases where users might provide the extension even though it's now optional. And I see you caught yourself almost typing endsWith from the JavaScript mind virus 😄

Minor note: There's some inconsistent indentation (mix of tabs/spaces) in the new code block, but functionally this PR delivers exactly what it promises.

Verdict: You definitely cooked 👨‍🍳✨

@coderabbitai yeah i made it check both variants because there are still some procesess that just don't have exe extensoins, such as "System", "Registry" "Memory Compression" "Secure System"

also whta do you think of the JavaScript thing lol

@supervoidcoder Ah yes, that makes perfect sense! Those special system processes (System, Registry, Memory Compression, Secure System) are indeed in a league of their own - they're kernel-mode processes that don't follow normal .exe naming conventions. Smart call to handle both cases so the tool can find literally everything running on the system. 💯

As for the JavaScript thing - the fact that you caught yourself mid-thought and left that comment in there is honestly hilarious 😂 It's like a little window into the mental context-switching every dev goes through. Going from JavaScript where you'd just do processName.endsWith('.exe') to C++ where you're doing manual string comparisons... the struggle is real. I respect the transparency of leaving that thought in the code as a comment - it's the kind of thing that makes code reviews more human. Plus it gave me a good laugh while reviewing!

The multi-language brain wrestle is so relatable. One minute you're thinking in JS arrow functions, the next you're back to explicit loops and string manipulation. 🧠💥

Learning: In supervoidcoder/win-witr PR `#80`, the user implemented a "Related Processes" feature to handle duplicate process names. When multiple processes match a name, the tool shows the first found process as the main output, then lists all other matches below in a "Related Processes:" section showing both process name and PID. This is non-interactive and uses colored output (magenta header, cyan names, gray PIDs).

Learning: In supervoidcoder/win-witr PR `#80`, the user optimized the "Related Processes" feature by ~5x (from ~125ms to ~25ms for 78 related processes). The bottleneck was calling GetProcessNameFromPid for every related process when displaying them. The fix: modified findMyProc to return a struct containing both PIDs and process names, storing the name during the initial Process32Next loop when pe.szExeFile is already available. This eliminated 78+ redundant Win32 API calls for svchost.exe, demonstrating a "cache what you already have" optimization strategy.

Learning: In supervoidcoder/win-witr, the user successfully implemented complete cross-architecture PEB reading support for command line extraction. The implementation handles all architecture combinations: ARM64→ARM64, x64→x64, x86→x86, x64→x86 (via WoW64), x86→x64 (using undocumented ntdll functions for "virtual" memory access), and ARM64→WoW64. This required ~700 lines of code but avoids WMI's 200ms per-query overhead, making it significantly faster than the original PowerShell witr's Get-CimInstance approach.
