AI Summary

This release introduces new testing filters for ctest and PHP, adds Maven Daemon support, and significantly improves git-diff and grep functionality. It also resolves numerous issues regarding BOM handling, TypeScript diagnostics, and hook configuration.

Key Highlights

Breaking Changes

  • Removed `--file-type` and `-t` flags from `rtk grep` (they were previously no-ops).
  • Native grep flags `-l` and `-m` are now honored in `rtk grep` instead of rtk's custom flags.

New Features

  • Added compact output filter for ctest.
  • Added PHP .phpt filter for php-src run-tests.php.
  • Added rtk mvnd support for Maven Daemon.

* **grep:** `rtk grep --file-type` and its `-t` short are removed. The option never reached the engine, so it was a silent no-op; `-t` now flows through, which means `rtk rg -t rust` filters by type while `rtk grep -t rust` returns grep's own `invalid option -- 't'`. `-l` and `-m` under `rtk grep` are likewise the native grep flags now rather than rtk's --max-len and --max.


### Performance Improvements

* **hook:** avoid Pi package barrel import ([322db4d](https://github.com/rtk-ai/rtk/commit/322db4da98219b15608d5b71eddf6338c48d693c))

* **grep:** trim comments and align the siblings of the flag change ([eb3f814](https://github.com/rtk-ai/rtk/commit/eb3f8148726f3725f1de5b3cb546991d2b562df9))
