* fix(#3096): enforce sequential Steps 7+8 + Edit-only discipline in ai-integration-phase

Root cause: Steps 7 (gsd-ai-researcher) and 8 (gsd-domain-researcher)
were listed without an explicit sequential constraint. An orchestrator
optimizing for speed could parallelize them since sections appeared
disjoint. gsd-domain-researcher's Write at finalization replaced the
full AI-SPEC.md with its in-memory copy (pre-researcher state), losing
Sections 3/4. Confirmed at 40% incidence (2/5 agents on a real run).
Recovery cost: one extra ai-researcher dispatch, ~18 min wall.

Fix:
  - Explicit 'MUST run sequentially' note on Step 7 (ordering note)
  - 'Wait for Step 7 to complete before spawning Step 8' on Step 8
  - Edit-only tool discipline injected into both agent prompts:
      'Use Edit exclusively - NEVER use Write on this file'
    prevents the last-writer-wins overwrite regardless of dispatch order

Suite: 7043/7043. Closes #3096.

* fix(lint): allow-test-rule for ai-integration-phase structural contract test

**`ai-integration-phase` Steps 7+8 now enforce sequential execution and Edit-only tool discipline** — when `gsd-ai-researcher` and `gsd-domain-researcher` were dispatched in parallel (an optimization an orchestrator could reasonably make since the sections appeared disjoint), `gsd-domain-researcher`'s `Write` call at finalization silently replaced the entire AI-SPEC.md with its pre-researcher copy, losing Sections 3/4. Confirmed at 40% incidence rate (2 of 5 agents on a real run). Fix adds an explicit sequential ordering note to Steps 7+8 ("MUST run sequentially — wait for Step 7 to complete before spawning Step 8") and injects Edit-only tool discipline into both agent prompts ("Use the Edit tool exclusively — NEVER use Write on this file"). Closes #3096.
