/**

|
* PreToolUse Hook: Pre-commit Quality Check
|
|
*
|
|
* Runs quality checks before git commit commands:
|
|
* - Detects staged files
|
|
* - Runs linter on staged files (if available)
|
|
* - Checks for common issues (console.log, TODO, etc.)
|
|
* - Validates commit message format (if provided)
|
|
*
|
|
* Cross-platform (Windows, macOS, Linux)
|
|
*
|
|
* Exit codes:
|
|
* 0 - Success (allow commit)
|
|
* 2 - Block commit (quality issues found)
