v0.3.1

Fixed

• Adopt the always-on and guard settings changed by another opencode process instead of overwriting them from a stale snapshot
• Resume warming for a session armed in the shared state file when it goes idle in a process that has not seen a message for it
• Skip a ping whose timer fired after the cache tier lapsed (sleep, suspend) instead of cold-writing the fork and stopping
• Count the last reply's uncached output as expected on the first ping, so a long final answer on a small context no longer reads as a lost cache
• Stop arming and pinging subagent (child) sessions
• Serialize state-file writes with a lock so concurrent opencode processes no longer lose each other's sessions
