Brooklyn Nicholson 84d81d258f fix(tour): an unanswered tour bridge no longer costs 45s per action
The renderer's `tour.request` handler ships in the desktop bundle, but the
tool is offered by the backend, and the two update on different clocks. A
desktop build older than the tour tool receives the event in a renderer with
no branch for it, so `tour.respond` never comes and the agent blocks for the
full 45s deadline — once per action the model tries. A single "give me a
tour" turn (targets, then narrate, then stop) stacked those waits into
minutes of dead air, which is what got reported against #89620.

Hold a session's first action to a deadline a working renderer cannot miss,
and let an unanswered probe mark the bridge unavailable for that session:
later calls return immediately with an error naming the actual fix instead
of stalling again. Once a client has answered, real actions get the full
deadline back, so a preview tour injecting into a live page still works and
one slow action no longer condemns a live client. The verdict lives on the
session record, so it dies with the session and a new one re-probes.

The same five-action sequence goes from ~225s of dead air to a single 10s
probe. Toolset gating is unchanged: removing the tool outright needs a
client capability declared at session.create, which prompt caching means
can only take effect for a new session.
