fix: prevent todo list mutations while a runner attempt is active

[charlesrhoward]

Summary

• reject todo item list edits when a job currently has an in-flight runner process
• preserve stable in-flight todo attribution by forcing pause-before-mutate semantics
• add smoke regression for edit-while-running behavior via todoRunner IPC

Validation

• pnpm run lint:desktop
• pnpm run typecheck
• pnpm exec playwright test tests/smoke/desktop.smoke.spec.ts -c playwright.smoke.config.ts --workers=1

Closes #81

Note

Low Risk
Small, localized guard in upsertJob plus a smoke test; behavior change is limited to rejecting edits during an active run.

Overview
Prevents mutating a job’s todo list while its runner process is active, throwing a clear error to enforce pause-before-edit and keep in-flight todo attribution stable.

Adds a Playwright smoke regression that exercises the todoRunner IPC flow: start a job, wait until isRunning, attempt to upsert with changed todoItems, and assert the update is rejected.
