Summary

scripts/cmux-next/chat-transfer-live.py is a live, end-to-end check that session.transfer.pull (#19359, #19364) moves an agent chat between two running cmux-next builds with its history, queue and draft. It uses the acpmux test agent, so it needs no real agent and no credentials. It drives each build's control socket and acpmux the way the app does:

1. Build A holds a chat with a reply, a running turn, two queued prompts and a draft, shown in A's chat tab.
2. Build B pulls it with interrupt.
3. It checks that B shows the chat in a bound tab, has the history, runs the queue once and in order, and holds the draft; that A's tab closed and A's copy is closed, having run none of the queue; and that a second pull moves nothing.

Testing

Ran on one fleet DEV build (twice; the second run after the review fixes) of feat-cmux-next (ffd9304, which includes #19364), launched in two capture slots of one Mac mini: RESULT PASS, every check ok. It finds each build's acpmux home by its exact build tag, and puts each home's config.json back after the run.

ok   A's tab shows the chat and B lists it as a chat record
ok   the record names A's acpmux socket
ok   A's chat has two prompts queued behind its running turn
ok   the pull moved the chat
ok   B shows the chat in a tab bound to its session
ok   A's tab for the chat closed
B user messages ['hi', 'until-cancel', 'queued a', 'queued b']
ok   B has the history and ran the queue once, in order
ok   B holds the draft ('unsent words')
ok   A's acpmux has the chat closed (closed)
ok   A ran none of the queue (['hi', 'until-cancel'])
ok   a second pull moves nothing
RESULT PASS

Found on the way, not fixed here: a chat whose folder no longer exists on the taking machine is refused (correct), but the app shows acpmux's CLI wording ("pass a new cwd via fork or edit session.json"). Follow-up: cx-xtg0.10.

scripts/verify-local.py: the swift-syntax, localization, localization-defaults and package-groups checks fail on files this PR does not touch (Linux host, base state). No app code changes.
