Child session creation was injecting permission: { question: 'deny' } which
conflicted with OpenCode's child session permission handling, causing subagent
sessions to hang with 0 messages after creation (zombie state).
Remove the permission override from all session creators (BackgroundManager,
sync-session-creator, call-omo-agent) and rely on prompt-level tool restrictions
(tools.question=false) to maintain the intended policy.
Closes#1711
Change promptAsync catch blocks to set status = "interrupt" instead of "error".
This distinguishes prompt errors from stale timeouts (cancelled) and TTL expirations (error).

Add permission: [{ permission: 'question', action: 'deny', pattern: '*' }]
to client.session.create() call to prevent background sessions from
asking questions that go unanswered, causing hangs.
