docs(shared): add PLAYGROUND-MAINTENANCE.md procedure

Documents the 4-track procedure for updating plugin playground HTML
when plugins are extended or upgraded:

- Track A: Plugin HTML change (parsers, renderers, surfaces)
- Track B: Shared design-system change (with vendor sync)
- Track C: Visual verification (screenshots + manual QA)
- Track D: Release (version bump + 3-doc rule)

Lives at marketplace root because the procedure crosses the
plugin/shared boundary. Marketplace-root CLAUDE.md gets a one-line
pointer under Konvensjoner so Claude finds it automatically in
future sessions.

Includes architecture diagram, common pitfalls (replace_all scope,
sync-without-testing, screenshot folder version mismatch, background
orchestrator degradation), and guidance on when to hoist inline CSS
to the shared DS vs keep it plugin-local.
