Greptile SummaryThis PR narrows Windows Bash hook rewriting so only directly invoked
Confidence Score: 5/5The PR appears safe to merge with no concrete changed-code defect identified. The new classifier is limited to Windows Bash hooks and preserves compound or interpreter-driven commands while still prefixing direct

| Filename | Overview |
|---|---|
| src/utils/hooks/windowsBashCommand.ts | Adds a conservative first-shell-word classifier for deciding when a Windows hook needs an implicit Bash interpreter. |
| src/utils/hooks/windowsBashCommand.test.ts | Covers preserved shell constructs, directly invoked script forms, quoting and escaping, plus real Bash execution. |
| src/utils/hooks.ts | Replaces the broad inline .sh match with the extracted Windows command classifier. |

In `@src/utils/hooks/windowsBashCommand.ts`:
- Line 7: Update the command classification logic in the Windows Bash command
helper to parse leading environment-assignment words separately, then prepend
bash for direct .sh invocations such as FOO=bar ./hook.sh. Preserve the existing
behavior for assignment-based commands that explicitly invoke bash, including
SCRIPT=./hook.sh bash "$SCRIPT", and add regression coverage for quoted
assignment values and the changed direct-script behavior.

In `@src/utils/hooks/windowsBashCommand.ts`:
- Line 16: Update the command parsing logic around the parameter-expansion check
in the Windows hook command utility so it continues past a complete leading
assignment word and recognizes the following literal .sh executable path.
Preserve the assignment text, support quoted script paths with spaces, and
retain regression coverage for both FOO="$BAR" ./hook.sh and FOO=${BAR:-value}
"./hook script.sh" cases.
