Loading a session's subagent transcripts all at once OOMs the daemon
worker on large Claude sessions (#5820: a 395 MB parent plus 269
sidechain transcripts, 757 MB total, crash-loops the worker). Stat the
sidechain files before reading any and leave them unread when the
parent plus sidechain transcripts exceed a replay budget (256 MB by
default, PASEO_CLAUDE_REPLAY_BUDGET_MB to override); the parent history
replays unchanged, which is the same state as moving the subagent
transcripts out of the way. Also parse the parent transcript once
instead of twice while rebuilding sidechain ownership.
