fix: skip Git Bash path detection on WSL

Browse Source 
On WSL, paths like /c/work/... are valid drvfs mount points, not Git
Bash drive-letter shortcuts. The existing code in isAbsolutePath() and
resolve() detected /c/ as a Windows C: path, converting drvfs paths to
C:/work/... which broke indexing entirely.

Fix: detect WSL via WSL_DISTRO_NAME or WSL_INTEROP environment variables
and skip the Git Bash /c/ -> C: branch on WSL. Native Linux path handling
continues as before.
