chore: prepare v0.4.1 release

- Fix ag search strategy to properly convert glob patterns to regex
- Pattern "*.py" now correctly converts to "\.py$" for ag's -G parameter
- Pattern "test_*.js" now correctly converts to "^test_.*\.js$"
- Ensures consistent file filtering behavior across all search tools
- Update search_code_advanced docstring to reflect current behavior
- Clarify file_pattern handling: all tools now support glob patterns consistently
- Clarify fuzzy parameter behavior: ugrep provides true fuzzy search, others use word boundaries
- Bump version to 0.4.1 in pyproject.toml and __init__.py
- Add comprehensive release notes for v0.4.1

-                     - grep: Basic pattern matching only
-                     For best compatibility, use simple patterns like "*.py" or "*.js".

-               - ugrep: Native fuzzy search with --fuzzy flag (true fuzzy search)
-               - Other tools: Word boundary pattern matching
-               For literal string searches, set fuzzy=False (recommended for exact matches).

         regex: If True, enables regex pattern matching. Use this for patterns like "ERROR|WARN".
                The pattern will be validated for safety to prevent ReDoS attacks.
