ci: add reusable validation template

[ChefGroep]

Summary

• add a manually runnable and reusable validation workflow with least-privilege permissions
• repair the npm lock entry required for deterministic npm ci
• apply the repository's configured Biome formatting and import-order fixes

Verification

• npm ci --ignore-scripts
• npm run check:ci
• git diff --check

Rust formatting and Clippy require the GitHub Actions toolchain because cargo is unavailable in the local environment.

Summary by CodeRabbit

• Chores

  • Added reusable automated validation workflows for Node and Rust formatting, linting, and quality checks.
  • Improved validation run management and permissions.

• Style

  • Standardized formatting, import ordering, line wrapping, and type-check annotations across examples and packages.
  • Clarified API declarations without changing their signatures or behavior.
  • Improved code consistency across JavaScript, TypeScript, and Rust components.

• Tests

  • Updated test formatting to align with project conventions.

📝 Walkthrough

Walkthrough

Adds a reusable GitHub Actions validation workflow. Reformats imports, API declarations, expressions, calls, exports, examples, tests, and Rust bitmap iteration across the repository. Runtime behavior and public API signatures remain unchanged.

Changes

Validation and formatting

Layer / File(s)	Summary
Reusable validation workflow .github/workflows/validation-template.yml	Adds manual and workflow-call triggers, read-only permissions, concurrency cancellation, Node quality checks, and Rust formatting and Clippy checks.
FFF API and source formatting packages/fff-bun/..., packages/fff-node/..., packages/shared/fff-api.ts	Reorders imports and exports, reformats API declarations and FFI expressions, and updates Bun examples and tests.
Pi package formatting packages/pi-fff/src/*, packages/pi-fff/test/*	Reformats source expressions, rendering logic, auxiliary-finder code, path validation, and a related test assertion without changing behavior.
Rust bitmap iteration formatting crates/fff-core/src/index/bigram_filter.rs	Changes flush_seen to use compile-time-sized eight-word chunks while preserving bitmap processing behavior.

CI: add reusable validation workflow template (Node + Rust)

⚙️ Configuration changes ✨ Enhancement 🐞 Bug fix 🕐 20-40 Minutes

AI Description

• Add reusable/manual GitHub Actions workflow for Node and Rust validation.
• Fix npm lockfile metadata to keep npm ci deterministic.
• Apply Biome formatting/import-order and fix directory autocomplete labeling.

High-Level Assessment

The following are alternative approaches to this PR:

1. Composite action for validation steps

• ➕ Encapsulates setup/install steps for reuse across multiple workflows
• ➕ Easier to version and consume across repositories
• ➖ Harder to express multi-job concerns (separate Node/Rust timeouts, concurrency) cleanly
• ➖ Less transparent job logs compared to a workflow-level template

2. Single workflow with a job matrix (node/rust)

• ➕ Centralizes shared settings like permissions/concurrency
• ➕ Can reduce duplication for common checkout/setup
• ➖ Node and Rust have different toolchain setup needs; matrix can become awkward
• ➖ Harder to tune per-job timeouts and steps without conditionals

Recommendation: Keep the reusable workflow approach. It preserves clear, separate Node/Rust jobs with independent timeouts and setup, while enabling reuse via workflow_call and manual runs via workflow_dispatch. Composite actions or a matrix would add complexity without strong payoff for this repo’s current needs.

index.tsFix directory suggestion labels and apply formatting cleanups +34/-85

Fix directory suggestion labels and apply formatting cleanups

• Fixes autocomplete suggestion construction so directory results use 'dirName' as the label (previously used 'fileName'). Also applies multiple Biome-driven formatting reductions and makes 'auxPool' a 'const'.

47-47: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Enforce the committed Cargo lockfile during Clippy.

If Cargo.lock is committed as the Rust dependency contract, add --locked. This makes Cargo fail when dependency resolution would change the lockfile. Cargo documents --locked for deterministic CI builds. (doc.rust-lang.org)

Proposed fix

-        run: cargo clippy --no-default-features --features zlob -- -D warnings
+        run: cargo clippy --locked --no-default-features --features zlob -- -D warnings
