test(bundle): drive the missing issue/pull number guards of every command handler and onPrLgtm through dist/index.js

[hivecommons-hive]

Test Improvement

Adds __tests__/bundle/missingNumberGuards.test.ts (27 tests), driving through dist/index.js the one arm every command handler shares and no bundle fixture had ever reached: the github context payload missing issue number guard (pull number in cc.ts/uncc.ts, pr number in onPrLgtm.ts) thrown before the first API call.

Claimed ground — exactly these 18 statements, all at 0 end-to-end hits on main @ 3fc21f2 and still at 0 after overlaying every open hold-gated bundle PR (#242–#341):

src/issueComment/{assign.ts:29, unassign.ts:25, cc.ts:26, uncc.ts:25, approve.ts:44, retitle.ts:26, close.ts:24, lock.ts:33, reopen.ts:21, milestone.ts:28, meow.ts:35, trigger.ts:207 (prepare)}, src/labels/{remove.ts:25, hold.ts:30, lgtm.ts:39, fixed.ts:70, prefixed.ts:146}, src/pullReq/onPrLgtm.ts:19.

• For each of /assign /unassign /cc /uncc /approve /retitle /remove /hold /lgtm /close /lock /reopen /milestone /meow /retest /help /kind: an issue_comment payload with issue.number deleted exits 1 and core.setFailed carries error handling issue comment: Error: github context payload missing issue|pull number: [object Object].
• For the hand-written commands that read nothing before the guard (/assign /cc /retitle /close /lock /reopen /milestone /meow /retest): the fake GitHub receives no request.
• jobs: lgtm on a pull_request synchronize payload with pull_request.number deleted fails with error handling pull request: Error: github context payload missing pr number.

Measured with npm run test:coverage:e2e on main @ 3fc21f2: src/ 77.9 % → 79.16 % lines; all 18 listed statements go from 0 to ≥1 hits. The file passes against both the committed dist/index.js (npx vitest run __tests__/bundle/missingNumberGuards.test.ts) and the source-mapped coverage bundle; eslint and tsc --noEmit clean. No src/, dist/ or workflow changes.

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.
