Fix release script pre-commit hook race condition (#2012)

## Summary

- Fixes the `rake release` task failing with "Unable to create
index.lock" error
- Root cause: Multiple pre-commit hooks running in parallel tried to
`git add` files simultaneously, causing a race condition for the git
index lock
- Solution: Use lefthook's built-in `stage_fixed: true` option instead
of manual `git add` commands

## Changes

- Updated `.lefthook.yml` to add `stage_fixed: true` to autofix, eslint,
and prettier hooks
- Removed manual `git add` calls from `bin/lefthook/prettier-format`
- Removed manual `git add` calls from `bin/lefthook/ruby-autofix`
- Added glob patterns to hook definitions for better performance

## Test Plan

- [x] Tested commit with multiple file changes (prettier formatted
`.lefthook.yml`)
- [x] Verified no `index.lock` errors occur
- [x] Confirmed files are properly re-staged after formatting
- [x] RuboCop passes with no violations

## Impact

This fix ensures that the release script can successfully commit version
bumps without encountering race conditions when multiple formatters try
to re-stage files.

## Summary by CodeRabbit

* **Chores**
* Added file-type globs to pre-commit hook configurations for autofix,
RuboCop, ESLint, and Prettier.
* Removed automatic re-staging of files after formatting and autofixing;
commands now leave staging unchanged.
  * Adjusted autofix completion message for clarity.
  * No functional change to trailing-newlines or pre-push checks.
