#4293 feat(harmonyos): verify foreground after open instead of trusting the launch line

Summary

On HarmonyOS, open reported success off the start ability successfully stdout line alone — on a locked screen the report said Opened while the screen showed the lock face, and the session kept reasoning from a state the device never entered. openHarmonyApp now polls the app state (up to 5s, reusing the FOREGROUND parsing from apps state) after the launch line: when the launched bundle does not hold the foreground, the result carries an open_not_foreground warning telling the caller to unlock first; --foreground mode escalates that to a hard failure.

10 files changed (app-lifecycle polling, result plumbing, tests).

Validation

• Head: 45a07a8e0 on a68693c72 (includes review-fix commit; help wording synced for both audiences per the flag-types rule).
• pnpm run typecheck, pnpm run lint, app-lifecycle tests, integration-progress --check, fallow, freerange: pass locally.
• Independent cold review: applied. CI runs the full gates on push.
