* Fix subagent announce race and timeout handling
Bug 1: Subagent announce fires before model failover retries finish
- Problem: CLI provider emitted lifecycle error on each attempt, causing
subagent registry to prematurely call beginSubagentCleanup() and announce
with incorrect status before failover retries completed
- Fix: Removed lifecycle error emission from CLI provider's attempt-level
.catch() in agent-runner-execution.ts. Errors still propagate to
runWithModelFallback for retry, but no intermediate lifecycle events
are emitted. Only the final outcome (after all retries) emits lifecycle
events.
Bug 2: Hard 600s per-prompt timeout ignores runTimeoutSeconds=0
- Problem: When runTimeoutSeconds=0 (meaning 'no timeout'), the code
returned the default 600s timeout instead of respecting the 0 setting
- Fix: Modified resolveAgentTimeoutMs() to treat 0 as 'no timeout' and
return a very large timeout value (30 days) instead of the default.
This avoids setTimeout issues with Infinity while effectively providing
unlimited time for long-running tasks.
