Remove shutdown wait on fileQueueSettled and silence known shutdown noise in CLI

[samuelstroschein]

Closes #4327

---

Note

Medium Risk
Touches CLI shutdown behavior by removing a best-effort background-queue settle and by monkey-patching console.error, which could hide unexpected errors if the regexes are too broad, but scope is limited to known shutdown messages.

Overview
Fixes CLI commands that could hang on exit by removing the shutdown wait on fileQueueSettled (deleting settleLastUsedProjectFileQueue and its usage in translate/validate).

Adds silenceKnownShutdownNoise() (called from main.ts) to suppress specific console.error messages from background file-queue processing when the DB has already been closed, reducing non-actionable shutdown noise.

Includes a patch changeset for @inlang/cli documenting the behavior change.
