N/A — fix reported while going through the GitHub App create-manifest flow.

Why this PR exists

• I am a maintainer / this is internal Roomote work

What changed

Creating a GitHub App through Roomote's manifest flow failed on GitHub with:

Default events are not supported by permissions: merge_group

The create-app manifest subscribed to merge_group without requesting the matching merge_queues repository permission that GitHub requires for that event. New apps now request merge_queues: read so the events and permissions stay aligned and the flow can complete.

How it was tested

• Updated and ran apps/web/src/trpc/commands/github/mutations.test.ts (11 passed)
• pnpm lint and web typecheck passed

Reviewed the GitHub App manifest change that adds merge_queues: 'read' to align with the merge_group default event. The permission is applied consistently to the GitHubAppManifest type, buildGitHubAppManifest(), and the test assertion, and read is the correct access level GitHub requires for the merge_group event. No other manifest definitions need the same update.
