Show Pi resource profiles in patchmill doctor

[rochecompaan]

Summary

• Added shared Pi resource profiles for run-once planning, development-environment, implementation, and triage invocations.
• Added read-only doctor Pi resource discovery and compact resource profile output.
• Integrated resource warnings and quiet-mode handling without changing required-check failure semantics.

Validation

• node --test src/pi/resource-profiles.test.ts src/cli/commands/run-once/pi.test.ts src/pi/runner.test.ts src/cli/commands/triage/dry-run-agent.test.ts src/cli/commands/triage/execute-agent.test.ts src/cli/commands/doctor/*.test.ts — 118 pass, 0 fail.
• npm test — 1051 pass, 0 fail.
• npm run lint:ts — passed.
• npm run lint:md — passed.
• npm run lint — failed only at format:check for unchanged plan/spec markdown files: docs/plans/2026-07-15-patchmill-doctor-pi-resources.md, docs/specs/2026-07-15-patchmill-doctor-pi-resources-design.md.
• Manual node bin/patchmill.ts doctor --quiet / doctor — resource blocks printed before the checklist when local required checks failed; failures were local Pi provider/auth readiness.
• Mutation check — no tracked changes and no Pi package install/update artifacts; provider smoke test created .patchmill/pi-agent/auth.json, which was removed after inspection.

Reviews

• Final Codex full-worktree re-review: pass.
• Final thermo-nuclear full-worktree second re-review: pass after accepted fixes.
