* fix(publish): make git operations idempotent
- Check for staged changes before commit
- Check if tag exists before creating
- Check if release exists before creating
* fix(ast-grep): add validation for incomplete function declaration patterns
- Add validatePatternForCli function to detect incomplete patterns like
'export async function $METHOD' (missing params and body)
- Only validates JS/TS languages (javascript, typescript, tsx)
- Provides helpful error message with correct pattern examples
- Update tool description to clarify complete AST nodes required
This fixes the issue where incomplete patterns would fail silently
with no results instead of providing actionable feedback.
- Add ast_grep_search for pattern-based code search (25 languages)
- Add ast_grep_replace for AST-aware code rewriting with dry-run
- Add ast_grep_analyze for in-memory code analysis (NAPI)
- Add ast_grep_transform for in-memory code transformation
- Add ast_grep_languages to list supported languages
