new manager tools mcp__hyperhive__{start,restart} that delegate to the
existing lifecycle::start / lifecycle::restart on the host. kill was
already at the manager's discretion; rounding out start + restart for
parity so day-to-day container care doesn't have to round-trip through
the operator.
guard: refuse self-targeting on kill/start/restart — the manager would
just be cutting its own legs. spawn (request_spawn) and config changes
(request_apply_commit) still go through the approval queue, since those
are the actual gate. prompt + claude.md updated to make the boundary
explicit. kill now also emits HelperEvent::Killed (it didn't before).
new mcp tool on the manager surface that queues a question on the
dashboard and returns the question id immediately. operator submits an
answer via /answer-question/<id>; the dashboard fires
HelperEvent::OperatorAnswered { id, question, answer } into the manager
inbox so the next turn picks it up.
also: fix async-form button stuck on spinner after successful submit
(refreshState skipped re-rendering, so the button was never re-enabled).
