audit fixes: RTK hook, settings unification, graphifyy, statusline

- Add RTK PreToolUse hook (rtk-rewrite.sh) and fix missing config
- Unify settings.json: merge hooks, marketplaces, model into project file
  so link.sh symlink is the single source of truth
- Add statusline: model, folder, git branch, context % progress bar
- Add graphifyy support: detect, install (pipx), lock, doctor, session-start
- Clarify ctx7/ruflo as standalone CLI (not MCP servers)
- Fix install-plugins.sh step numbering (duplicate step 6)
- Add version check in session-start (local vs origin/master)
