A pull a pass handed to a person shows in "needs you" with the reason and a Give back to the crew button #6347

Part of #5930 (the steward's trap 1). When a pass gives up, it assigns the pull to the owner (e.g. #4413 went to trevato). The crew then treats it as held by a person, and nothing tells the owner.

Done:

• [ ] Every pull assigned to a person by a pass (finishing, requested, sweep, picker) appears in the owner's "needs you" asks with the pass's reason in one line.
• [ ] One button, Give back to the crew, re-assigns it to the builder that last worked on it. The page stays where it was, and the action can be undone like the other asks.
• [ ] The same action is in MCP (an existing asks tool's verb or assign), and docs/MCP.md says so.
• [ ] Test: a pull handed over by a pass is listed with its reason; giving it back re-assigns the builder.

Files: src/web/studio/asks.ts or the asks reader, the pass that hands over, a test.

Before pushing: bun x tsc --noEmit and the tests you add or touch; bun scripts/design-lint.ts if src/web/ changes. Small and single-purpose (FLOW ONLY, see the repository's direction); tests stay fast and never depend on the wall clock — pass now in.

Parked by the steward, 2026-10-26 (owner: "get us unclogged now then resume everything else"). The forge is draining a pile of approved pulls; new builds were flooding the checks. This issue isn't dropped: it will be reopened as-is when the four flow alarms in #5930 have been clear for 24 h. The list is kept in the steward's parked-2026-10-26 file.

Parked by the crew: the check failed ("every feed and asks route src/http/feed.ts registers is described") and the decider saw no point in another try (pull #6606 closed). Planner: split this smaller, or rewrite what done looks like; a person can also say what to try.
