test(bundle): drive label-sync's refused-write and description-drift arms through dist/index.js

[hivecommons-hive]

Test Improvement

Adds __tests__/bundle/labelSyncFailureArms.test.ts (new file; nothing else touched), driving the failure arms of src/cronJobs/labelSync.ts through the committed dist/index.js against the fake GitHub API:

• a workflow_dispatch jobs: label-sync run where POST /labels answers 403: one core.error per refused built-in, every create still attempted after the first refusal (write() catch, lines 107-109), then the single TypeError: error handling cron job: Error: 16 label(s) could not be synced: … failure (line 94)
• the one existing label, kind/bug, has the configured description missing and no configured colour, so the only write that succeeds is PATCH /labels/kind%2Fbug with { description } alone (drift() line 134)

Measured with npm run test:coverage:e2e on main @ 3fc21f2: labelSync.ts 85.41 → 97.91 % lines (only line 55 remains). Unit coverage of the file is already 100 %.

Cluster: labelSync refused writes / description drift — disjoint from the held bundle PRs (#242 cron jobs input, #283–#310 issue_comment commands, plugins and handlePullReq).

Important

Held for human review by the hive's ACMM level gate.

This PR was opened by the "quality" agent while Hive policy required a human checkpoint for that agent. Non-outreach agents are held at ACMM L3–L5; the outreach agent is always held because it publishes project-facing communication.

Hive will keep the hold label until a human removes it. Operators can make a deliberate one-off release during an ACMM level change with release_level_holds=true, but level changes never release this hold automatically.

Please add a kind label with /kind failing-test or /kind cleanup.

build-test is red here for a baseline cause this PR's diff does not touch: all 81 test files pass, and the job exits 1 on a single vitest Unhandled Error — assert(err.code !== "ERR_TLS_CERT_ALTNAME_INVALID") originating in __tests__/issueCommentTest/meow.test.ts (runs 37234340602, 37234245909 on f5e5587). This PR only changes __tests__/bundle/labelSyncFailureArms.test.ts.

Tracked as shared incident #294; fix is #287. Deferring — no re-runs or pushes to this branch until that lands.
