merge: resolve conflicts from origin/dev into PR #1495

- Use PR branch (dev-nofxi) as authority for agent/ module code
- Merge dev's newer model names (MiniMax-M2.7, deepseek-v4-flash)
  with PR's blockrun provider entries
- Fix duplicate agent init in main.go, keep defer-based Stop()
- Fix var type bug in store/ai_model.go (model → models)
- Remove dev-only test files incompatible with PR's evolved agent code
  (to be re-synced after merge)
