fix(runner): also send unchanged --lines-file target with the run

[Atchyut Preetham Pulavarthi (theonly1me)]

Overview of Changes

Delta shipping withholds any file whose content hash matches what the runner already holds. A page object named by --lines-file that has not changed since the last run hashes equal, so it was dropped from the payload and the platform refused the run with A selection must name a file carried in files.

• Always send the file a selection names, alongside the entry point and package.json, so an unchanged --lines-file target still travels with the run
• Cover buildRunFileDelta keeping a selection's file while still withholding an ordinary unchanged one
• Cover handleRunnerRun sending the --lines-file target against a runner that already holds it

Testing

bun run typecheck
bun run test
bun run lint:fix
bun run format
bun run knip

bun test gives 1831 pass 0 fail. The other four give exit 0.

• Reverting the alwaysSent addition fails the buildRunFileDelta test, and reverting the selectionPath wiring in submitRun.ts fails the handleRunnerRun test.

Walkthrough

The runner passes the selected file path to buildRunFileDelta. The selected file is sent in full when unchanged and already held by the runner. Other unchanged files continue to use content hashes. Unit and flow tests cover this behavior. A changeset documents the update.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to e5e38

This change ensures an unchanged file named by --lines-file is included in the run payload, preventing that run from being rejected; no actionable merge-blocking risk remains beyond normal checks and review.
