test: run Chunk 2 and governance behavioral tests; fix failing rules

13 manual scenarios run across instructions and governance layers (two
rounds for failures). Fixed four rules that lost to RLHF defaults:

- Exploratory question format: tightened with boundary framing; added
  @import CONTEXT.md to repo CLAUDE.md and a standing rule to check
  docs/adr/ and ROADMAP resolved entries before answering design questions
  (3-round iteration to resolve)
- File-edit intent: added counter-example to stop clarification-seeking
- Push confirmation: reframed as "do not call the tool" not "ask first"
- Secrets rule: extended to cover credential reproduction in response
  text and usage examples, with explicit placeholder requirement

Scenario 4 (push confirmation) inconclusive — no remote configured.
Governance scenario 3 (HITL on real infra) untestable — Nginx not installed.
Both share the same root cause: agent delegates to permission system.

Also corrects stale skill list in docs/spec/overview.md (12 actual
deployed skills vs 16 names previously listed).
