One shared subagent tracker for Claude, Codex and Grok chat rows (#27228)
* test(native-chat): pin each agent's subagent row writes before unifying the rosters * refactor(native-chat): one shared subagent tracker owns every agent's subagent rows Claude, Codex and ACP (Grok) each kept their own subagent roster with drifted rules. They now only report what they observe; one tracker decides grouping, runs, names, state, sweeps, retention, row writes and restart inheritance. The golden row-write tests from the previous commit show each rule change. * fix(native-chat): one entry per subagent, derived lookups, ACP end stamped in its session-end write Review round 1: a resumed child keeps its one entry and reopens it where it is listed (the chat draws one section per child, anchored at the first row naming it), every lookup is read from the rows, the no-turn row is never released, and ACP's session end stamps its live children inside the session-end write instead of writing rows ahead of it. * fix(native-chat): derive the no-turn group, end a foreground run with the turn that started it Review round 2: the row no turn owns is recognised from its id (a stored flag was lost when an earlier run's row was first reached through one of its children), and a turn's end settles the foreground runs it started wherever their child is listed. * fix(native-chat): count an inherited subagent row as settled history when a lookup loads it A read-only lookup could load an earlier run's settled row that retention never saw, so it was never released and a fresh settled row was released in its place.
