Bound the registration poll by elapsed time, not by attempt count.
The loop runs Math.ceil(REGISTER_BUDGET_MS / REGISTER_POLL_MS) = 40 attempts. Each attempt awaits herdr("agent.get", ...), which uses the default PLAIN_TIMEOUT_MS of 5000 ms in lib/herdr/client.ts (Line 34). If herdr accepts connections but answers slowly, one attempt costs up to 5250 ms, so the loop can run about 210 s. The constant name and the comment promise a 10 s budget, and pane:spawn holds the caller for the whole time.
Add a wall-clock deadline and a per-probe timeout.

…nvite notes Rebased onto #117 (the picker-conformance omitBehavior gate). rt pane peek takes a required pane id, which is discovered via rt pane list, so it declares omitBehavior { exempt } like the other agent-facing verbs. inviteText now collapses lone CR, CRLF and the Unicode line separators, not only LF, so a note can never break the one-line /chat:join invariant (CodeRabbit).

The six wrapper signatures re-typed their payloads and return data by hand, so the contract in commands.ts and the wrappers could drift with no compile error. Each wrapper now takes Commands[cmd]["payload"] and returns Commands[cmd]["data"], the same source of truth the daemon handler reads and the pattern agentStart already uses. A contract change now fails tsc at every call site instead of shipping a mismatched payload (CodeRabbit). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Return Herdr failures after the fallback attempt.
Line 375 ignores a failed Enter nudge. Line 377 converts an unavailable or invalid follow-up agent.wait response into delivered: "queued".
Return herdrError for these failures. Keep queued only for timeout or agent_prompt_stalled. Return refused for agent_blocked.
