copilot-swe-agent[bot]androbbyrussell 6b789c8bd6 fix(git plugin): include git exec path in version cache key

Robby RussellandClaude Fable 5.1 984d07a53b perf(git): cache the git version used for alias selection 
`git version` was forked on every startup so that four aliases could be
picked according to the installed git. Cache the version in
$ZSH_CACHE_DIR for a day, keyed on the git binary's path and mtime, so a
different or upgraded git is picked up right away and the fork otherwise
happens once a day.

Measured on macOS arm64, zsh 5.9: git.plugin.zsh 9.2 ms -> 2.0 ms per
interactive start.
