docs(hooks): close compacting with the turn's state, not the trigger's - #767

Conversation
Claude Code 2.1.300 compacts an idle conversation before its prompt cache expires and hands the mod that compaction as `auto`, the trigger a mid-turn one carries. Closing every `auto` with `busy` left the card on the spinner with no Stop to follow. The closing report is now the turn's state: `busy` while a turn is open, `done` when none is.

Claude Code 2.1.300 compacts an idle conversation before its prompt cache expires and reports it as `auto`, the trigger of a compaction inside a turn. The mod closed every `auto` with `busy`, and with no turn open and no Stop to follow, the card sat on the spinner until the next prompt. The closing state is now the turn's: the mod follows turn.start and turn.complete and closes with `busy` while a turn is open, `done` when none is. The existing `auto` tests open a turn first, since the contract now keys the closing state on it (lichdotdev/lich#767).

Summary
Claude Code 2.1.300 compacts an idle conversation before its prompt cache expires ("Compacted while idle, before the prompt cache expired"). It prepares the summary under a
precomputetrigger and applies it through the same path as a mid-turn reactive compaction, sosession.compactreaches lich-plugin's mod withtrigger: "auto". The mod closed everyautowithbusy, and with no turn open there is noStopto follow: the card stayed on the spinner until the next prompt.The contract now says the closing report is the turn's state (
busywhile a turn is open,donewhen none is), and the table gains the idle row. No backend change: lich already reads adoneaftercompactingwithout raising a "has finished" notification.The client side lands in lichdotdev/lich-plugin#77.
