docs: freshen ROADMAP + ARCHITECTURE content + README notable-contrib counts

- ROADMAP.md: 8-themes -> 11-skins in status snapshot; replace stale per-file
  LOC architecture table with role descriptions + CI gate list (ruff/shard/
  browser/docker); note LOC drifts.
- ARCHITECTURE.md: refresh File Inventory — drop chronically-stale per-file LOC,
  add missing modules (state_sync.py, updates.py, i18n/login/icons/sw.js,
  pyproject.toml, ctl.sh, CONTRIBUTORS.md), refresh test count to ~7,150.
- README.md: update the 8 'Notable contributions' blurb headers (PR counts +
  release ranges) to match the regenerated tally.
