test: rewrite 5 plan-mode E2E tests on the real-PTY harness

Browse Source 
Replaces SDK-based assertions with runPlanSkillObservation contract. Each
test launches real claude --permission-mode plan, invokes the skill, and
asserts the outcome reaches 'asked' or 'plan_ready' within a 300s budget
(no silent Write/Edit, no crash, no timeout).

Affected:
- test/skill-e2e-plan-ceo-plan-mode.test.ts
- test/skill-e2e-plan-eng-plan-mode.test.ts
- test/skill-e2e-plan-design-plan-mode.test.ts
- test/skill-e2e-plan-devex-plan-mode.test.ts
- test/skill-e2e-plan-mode-no-op.test.ts (inPlanMode: false; tests the
  preamble plan-mode-info no-op path)

test/e2e-harness-audit.test.ts — recognize runPlanSkillObservation as a
valid coverage path alongside the legacy canUseTool / runPlanModeSkillTest.

test/helpers/touchfiles.ts — point the 5 plan-mode test selections and
the e2e-harness-audit selection at test/helpers/claude-pty-runner.ts
instead of the deleted plan-mode-helpers.ts.

Proof: bun test EVALS=1 EVALS_TIER=gate on these 5 files runs sequentially
in 790s and passes 5/5. Same tests were 0/5 on origin/main, on v1.0.0.0,
and on this branch with the SDK harness.
