Remove claude_ctx_py/assets/ from git tracking and make it a build
artifact regenerated by `just bundle-assets`. This eliminates the
confusing dual-copy situation where both repo root and bundled assets
were tracked and had diverged.
Changes:
- Remove claude_ctx_py/assets/ from git (now in .gitignore)
- Add plugins/ to sync script for domain-specific packages
- Make `just build` depend on bundle-assets
- Document asset workflow in CLAUDE.md
- Reorganize agents: promote 5 from inactive, demote 2 to inactive
- Update dependencies.map with comprehensive agent mappings
