feat: add .gitignore sync to dev-tools:sync
- Add GitIgnore namespace with Reader, Classifier, Merger, Writer classes - Reader reads .gitignore entries from both package and project - Classifier classifies entries as directories or files - Merger merges, deduplicates, and sorts entries - Writer writes normalized .gitignore file - SyncCommand now syncs .gitignore entries automatically - Entries are sorted: directories first, then files, alphabetical within each group Implements: #12
