* fix(infra/agents): session-routing guard for coalesced gateway restart continuations (#86742)
When two sessions issue gateway.restart with continuationMessage close
together, the scheduler Path B updatePendingRestartEmitHooks
unconditionally overwrote the existing pending hooks, silently dropping
the first sessions continuation and potentially routing the second
sessions continuation back to the first session (CWE-200 finding
flagged by aisle-research-bot on prior attempt #74443).
Add a session-routing guard: scheduleGatewaySigusr1Restart now accepts
an optional sessionKey and tracks the pending restarts owning session.
Coalesced callers from a different session are rejected at the hook-
update step and the new ScheduledRestart.emitHooksQueued: false field
surfaces the drop to the caller. The gateway tool propagates this as
continuationQueued: false in the tool response, matching #83370 narrow
report-only surface.
Same-session debounce/replace and legacy hookless callers behave the
same as before.

Preserve the Codex post-tool continuation guard for raw reasoning completions and streamed reasoning progress so valid post-tool synthesis stays on the intended completion watchdog instead of falling through to terminal idle behavior.
Verified with focused Codex watchdog tests, test typecheck, scripts lint, autoreview, and CI run 27086637988.
