External review on PR #4074 noted that adding setSessionAgent for child
sessions left sessionAgentMap holding entries after the session was
deleted or after the sync call_omo_agent executor cleaned up other
owned state. The map only grows; entries never get reused but they do
accumulate across long-running plugin instances.
Close both gaps:
- BackgroundManager.handleEvent for session.deleted now calls
clearSessionAgent for the deleted session id on both the early-return
no-task branch and the cascade tail. This pairs with the existing
clearDelegatedChildSessionBootstrap and SessionCategoryRegistry.remove
so all owned session state is dropped together.
- sync-executor finally for createdSessionForExecution now calls
clearSessionAgent alongside the existing subagentSessions,
syncSubagentSessions, and deleteSessionTools cleanup so sessions this
executor created cannot leak their agent mapping.
Adds focused tests:
- BackgroundManager.handleEvent - session.deleted cascade > should
clear session agent state for deleted sessions to prevent map leak
- executeSync > registers child-session bootstrap and tracked prompt
state before sync prompt dispatch (extended assertion for cleanup)
Two adjacent gaps cubic flagged on the previous diff:
1. spawner.startTask stored input.agent (potentially prefixed with sort
marker and ZWSP) in setSessionAgent, but the prompt body used the
stripped/normalized form. The session-agent registry therefore did
not match what promptAsync actually dispatched. Capture the
normalized agent once at the top of startTask and use it for
setSessionAgent plus the launch log lines.
2. manager.startTask wrote setSessionAgent(sessionID, input.agent)
before the cancelled and stale-attempt cleanup branches, but those
branches only cleared subagentSessions and the delegated bootstrap.
The session->agent mapping survived as orphan state after an aborted
launch. Call clearSessionAgent inside both early-return paths so
nothing remains tied to a session we just aborted.
Adds focused tests for both: spawner persistence parity with promptAsync
and manager cancellation cleanup leaving getSessionAgent undefined.
Three coupled gaps surfaced after the initial spawn fix:
1. fallback-retry-handler dropped task.skillContent and
task.sessionPermission when rebuilding LaunchInput, so the retried
background task lost the delegated system prompt and question-deny
permission rule.
2. manager.startTask never bound the child sessionID to the resolved
agent via setSessionAgent, leaving runtime fallback and other hooks
with no idea which agent owned the new child session.
3. The fallback-to-general path in spawner.ts rebuilt the prompt body
without going through buildFallbackBody, so bootstrap state, session
tools, and session agent updates drifted apart.
Persist skillContent and sessionPermission on BackgroundTask, bind
setSessionAgent/updateSessionAgent at session creation and on fallback,
and route the FALLBACK_AGENT retry through buildFallbackBody so the
prompt body, bootstrap tools, and session registries all agree.

Preserve delegated child prompt/bootstrap metadata for early runtime fallback before OpenCode has persisted the first user turn. Bind prompt gate calls to the SDK session receiver and keep completed background task lookup visible across plugin manager instances.
Replace the inlined parent-wake coalescing logic in manager.ts with delegation to the ParentWakeNotifier extracted in c1ccf8d09. The four timer Maps and the related methods now live in their own module with a narrow public API, while BackgroundManager retains the wiring point and the enqueue-callback bridge.
Closes HIGH-9 (step 2: integration)

Extracts the parent-wake coalescing logic (pending/dispatched wake maps,
timers, notification reply assembly) from manager.ts into a standalone
ParentWakeNotifier class. Takes dependency-injected client, directory,
and an enqueueNotificationForParent callback, so the manager can delegate
parent-wake state to a narrow API.
This commit only introduces the new module; wiring manager.ts to use it
is a follow-up commit so the refactor stays atomic (HIGH-9 step 1 of 2).

- Fixes BackgroundManager to launch promptAsync before invoking the blocking tmux callback.
- Adds regression test to ensure promptAsync is called before tmux callback.
