feat(workflows): add database branch isolation with git worktrees
Add comprehensive documentation for combining git worktrees with database branches
for true feature isolation across Neon, PlanetScale, Supabase, and local Postgres.
Changes:
- examples/commands/git-worktree.md: Add database branch detection and quick reference (~90 lines)
- examples/workflows/database-branch-setup.md: New complete guide with TL;DR and provider workflows (349 lines)
- english-ultimate-claude-code-guide.md: Add section 9.12 "Database Branch Isolation with Worktrees" (~95 lines)
- CHANGELOG.md: Add v2.4.0 release notes
- README.md: Update version to 2.4, line count to 9500+, add source attributions
Architecture: Progressive disclosure pattern (concise command → complete workflow guide)
