v0.2.0 — resident plugin tools + format guard

• Fork of xiaobright/dsh-anchored-standard with two local additions:
  • residentTools: antigravity_agent / antigravity_agent_status / vision / web_search visible right after promotion
  • format-guard: fixed per-turn format/continuity guidance injected from the second real user message on
• First-request RL anchor unchanged: one-sentence system prompt + bash/str_replace_editor, no auto-injected context
• Zero-dependency health check: npm run check
• Real-session example (sanitized) in docs/case-vna.md
