Launch expired timer commands without blocking other timers or requests. Collect their direct children before normal idle exit and preserve immediate EXECUTE and unmatched CANCEL-TIMER behaviour. Update timer command tests and operator documentation. AI assistance: OpenAI Codex and Claude Opus assisted with implementation, review and validation. The human contributor approved publication.

Summary
A slow timer command now allows other timers and timer requests to proceed. The daemon collects its direct children and waits for them before its normal idle exit. Immediate EXECUTE and unmatched CANCEL-TIMER commands retain their synchronous behaviour.
Evidence
Compatibility
Timer commands may now overlap, including successive invocations of the same timer name. The manuals and upgrade notes explain that scripts which require serial execution must arrange their own locking.
Closes #3115.
Prepared with OpenAI Codex and reviewed with Claude Opus.
