chore: read the request state from the event instead of threading it alongside

[Nic-Polumeyv]

RequestState is passed as an (event, state) pair through 16 functions in runtime/server, and the request store exists to carry the same pair to $app/server code. Every function that has the event already has the request, so both are redundant.

respond.js now registers the state in a WeakMap keyed by event.request and get_state(event) reads it back. The request is the one object that exists once per request and survives every { ...event } copy, so nothing is added to the event itself; the live-query event replaces request and re-attaches. With the state reachable from the event, the store has nothing of its own left: with_request_store({ event, state }) becomes with_event(event), get_request_store() becomes get_event(), and RequestStore is gone. The 16 signatures take event alone; internal_respond, internal_fetch and fork_state_for_subrequest still take state because they run before the event exists.
