Fixes#1521. When hook matcher patterns contained regex special characters
like parentheses, the pattern-matcher would throw 'SyntaxError: Invalid
regular expression: unmatched parentheses' because these characters were
not escaped before constructing the RegExp.
The fix escapes all regex special characters (.+?^${}()|[\]\) EXCEPT
the asterisk (*) which is intentionally converted to .* for glob-style
matching.
Add comprehensive test suite for pattern-matcher covering:
- Exact matching (case-insensitive)
- Wildcard matching (glob-style *)
- Pipe-separated patterns
- All regex special characters (parentheses, brackets, etc.)
- Edge cases (empty matcher, complex patterns)
- Add snake-case.ts: objectToSnakeCase, objectToCamelCase utilities
- Add tool-name.ts: transformToolName with PascalCase conversion
- Add pattern-matcher.ts: findMatchingHooks for hook config matching
- Add hook-disabled.ts: isHookDisabled for hook config validation
- Add temporary stub types at src/hooks/claude-code-hooks/types.ts
- Export all new utilities from src/shared/index.ts
Stub types will be replaced with full implementation in Task 1.
