test(bundle): drive /assign with argument users and /milestone set-by-title through dist/index.js

[hivecommons-hive]

Test Improvement

Adds two cases to __tests__/bundle/bundle.test.ts, next to the existing bare /assign and /milestone clear ones:

• /assign @octocat @stranger → the only write is POST issues/1/assignees with { assignees: ['octocat'] }; the stranger (no membership, no collaborator status, no prior comment) is dropped. The per-user authorization reads are not re-asserted — test(bundle): drive /cc /uncc /unassign /retitle /lock /reopen through dist/index.js #238's /cc cases own getOrgCollabCommentUsers.
• /milestone Sprint 2 → collaborator read, GET milestones, PATCH issues/1 with { milestone: 7 } (title with a space, matched from the rest of the command line).

The separate assignAndMilestone.test.ts (14 cases, copied helpers) was dropped on review: the rest repeated assign.test.ts, milestone.test.ts, errorPaths.test.ts:69/84 and command.test.ts:320.

Verification on main @ a270568: npx eslint, npx tsc --noEmit, npx vitest run __tests__/bundle/bundle.test.ts -t "argument users|title matches" — 2 pass.

Filed by quality agent (hold-gated mode). Human review required.

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 automatically remove the hold label once current policy no longer requires a level hold for "quality". If this is an outreach PR, a human must review it and remove the label.

All 14 cases repeat assign.test.ts, milestone.test.ts, errorPaths.test.ts:69/84 and command.test.ts:320. The bundle tests already cover both commands (bare /assign at bundle.test.ts:462, /milestone clear at :825).

1. Cut to at most two cases (/assign @a @b, /milestone <title>) or close this.
2. The argument-user checks run the same getOrgCollabCommentUsers code as #238's /cc cases, which is being merged. Don't duplicate them here.

[hivecommons-hive]

Addressed: cut to the two cases (/assign @octocat @stranger, /milestone Sprint 2), now inline in bundle.test.ts beside the bare /assign and /milestone clear tests using the shared comment/repo/token helpers; the /assign case asserts only the write and leaves the per-user authorization reads to #238's /cc cases. Separate file deleted. Rebased on main @ a270568.
