[Bug] Windows path handling broken in bash tool execution

Bug Description
In latest versions, on Windows 10 the claude cli gets to this weird state when in middle of the work it cannot run anything, or it cannot find a folder that exists, especially in format c:\something\else, it shouldn't be so hard to do a transformation of the path based on which OS is this running on..

Bash(dir "C:\Git\KM\keen_auth\lib" 2>&1)
⎿  Error: Exit code 2

● Bash(test -d /c/Git/KM/keen_auth && echo "exists" || echo "not found"; test -d /c/Git/KM/keen-auth && echo "exists" || echo "not found")
⎿  Error: Exit code 1

● Read 2 files (ctrl+o to expand)

● Bash(cd "C:\\Git\\KM" && ls 2>&1)
⎿  Error: Exit code 2

● Read 1 file (ctrl+o to expand)

● Bash(pwd 2>&1)
⎿  Error: Exit code 1

● Bash(echo hello 2>&1)
⎿  Error: Exit code 1
