Salvage stub plan findings as an incomplete report

[TheGreatAxios]

Summary

• Counsel and intent=plan workers require Findings substance (files/paths, acceptance criteria, non-goals, risks, ordered steps). Four headings with stub Findings salvage as incomplete-report, not an attachable plan.
• hasReportEnvelope stays heading-presence only. Implement and review envelope completeness is unchanged. Gaasbot is not armed (modelRole === "plan" is not the key).
• Wait JSON still carries stop_reason: incomplete-report so the parent does not treat a stub plan as a clean complete.

Verification

• bun run typecheck, bun run build, and bun run test pass
• bun run check passes (6895 tests, 0 fail)
• Targeted: bun test ./src/subagent/index.test.ts ./src/subagent/nudge-director.test.ts ./src/prompts.test.ts ./src/agent/directors/skywalker/package.test.ts ./src/subagent/agent-fleet.test.ts (250 pass, 0 fail)

Independent critic — request changes

Stub salvage wiring matches CL-7756 (cycle 1 nudge, cycle 2 incomplete-report-stop, implement/review unchanged, gaasbot unarmed). Do not merge until the Findings classifier is heading-only.

Blocking: classifyPlanSectionLine matches /\bsteps\b/ and /\brisks?\b/ anywhere on a Findings line. A real five-section plan whose Acceptance criteria says “The worker completes the salvage steps.” is classified as a steps heading, AC is truncated empty, and later ### Ordered steps is ignored → hasPlanFindings false → salvage. Tests only use a keyword-safe PASS_PLAN_ENVELOPE.

Fix: section labels must match heading or numbered-item starts, not body prose. Permanent tests: five-section plan with “steps” (and separately “risks”) in an earlier body still completes; counsel numbered labels with following-line substance complete.

Independent critic (re-review of d24f80c)

Prior blocking classifier bug is fixed. Mid-sentence “steps”/“risks” no longer open plan sections. Stub salvage, implement/review, gaasbot-unarmed, and heading-only envelope still hold.

Merge.
