v2.0.1 — Patch: config-corruption protection & repair

Patch release: fix duplicate-loader-entry crash & add config recovery

Fixes the crash caused by hot-installing a plugin that is already in dsh.profile.bundles
(duplicate loader entry id → dsh web fails to boot). Adds tooling to diagnose and recover
from config corruption.

Fixed

• Hot install now rejects bundles already managed by dsh plugin — no more duplicate
  insert rows in cordis.patch.yml, no more boot crash (duplicate loader entry id).
  Use dsh plugin --profile web add|remove for those instead.

Added

• dsh-web repair — diagnose & auto-fix common config corruption:
  • duplicate entry ids in cordis.patch.yml (dedup, keep first)
  • ghost bundles in dsh.profile.bundles (remove missing packages)
  • dsh-web-hot state out of sync (reset to match config)
• dsh-web health-check — after restart, verifies port + config tree; tells you
  whether the problem is the process or the config (stop looping restarts on bad config).
• Auto config backup — install/remove/repair back up cordis.patch.yml &
  state before changing them (kept in profiles/web/backups/, last 10).

Docs

• README bilingual: added technical architecture section (components, hot-install &
  safe-restart data flows, env dependencies).
