- Replaced standard and tokio mpsc channels with flume channels across workspace crates to simplify thread synchronization.
- Swapped standard Mutex guards for parking_lot Mutexes to avoid manual lock poisoning handling and improve performance.
- Declared workspace-wide dependencies for flume and parking_lot in root and member Cargo manifests.
- Replaced custom fast-walk and fs-cache implementations in pi-natives with a new dedicated pi-walker library.
- Integrated the thread-safe, parallel pi-walker library across pi-natives, pi-shell, pi-uu-grep, and uu-find.
- Rewrote file search, fuzzy finding, and glob-matching logic to leverage pi-walker configurations and visitor traits.
- Optimized shell process tracking in pi-shell by replacing global descendant-diff logic with an isolated, per-run SpawnRegistry.
- Added parallel rayon-based walking and optimized fast paths for directory scanning and entry classification.
- Added a platform-native fast filesystem traversal implementation leveraging `getattrlistbulk` on macOS, `getdents64` and `statx` on Linux, and `NtQueryDirectoryFile` on Windows.
- Integrated the fast traversal path as a preferred, high-performance fallback before standard walk operations in both cache collection and streaming search routines.
- Consolidated grep search logic by extracting a unified file-matching helper to support both standard and fast-walk execution paths.
- Introduced platform-specific Windows system dependency configurations and unit tests validating correct hidden-file filtering during scanning.
- Added Silver.ttf TrueType font support to `pi-natives` with automated fallback logic for bitmap font rendering.
- Implemented wide code point detection and cell-width calculation to improve CJK character handling and layout.
- Introduced dynamic font-aware preflight probing via `resolveShapeForText` and `renderabilityProbeText` for better font selection.
- Enabled semantic emoji folding and improved text normalization to handle non-Latin characters and emoji filtering.
- Switch build profile to `panic = "unwind"` to allow catching panics in vendored uutils code.
- Add `run_caught` to wrap utility execution in `catch_unwind`, converting panics into non-zero exit codes.
- Update `pi-natives` to distinguish between recoverable utility panics and fatal process crashes, preventing recovered panics from appearing in user-facing crash reports.
- Added an `fd` command-line utility for searching the filesystem.
- Implemented file filtering capabilities for type, size, modification time, and ownership.
- Integrated directory traversal and ignore-pattern support for search optimization.
- Registered the builtin in the shell and added comprehensive integration tests for filtering and globbing.
- Introduced `pi-uutils-ctx` to manage thread-local I/O redirection, environment context, and path resolution for in-process utilities.
- Integrated a suite of vendored coreutils (cat, find, grep, head, ls, mkdir, mv, rm, sort, tail, uniq, wc) as shell builtins.
- Added infrastructure for command cancellation, streaming I/O, and locale-aware error reporting within the shell environment.
- Configured shell-side dispatch logic to route commands through the new utility context, enhancing performance and binary integration.
- Enabled Julia language support by adding a sub-syntax definition file.
- Integrated the new syntax into the highlighter by updating the syntax set builder.
- Configured the dependency to support YAML syntax loading via syntect feature flags.
