nntrivi2001 5cb70d702b perf: cheaper ingest — no re-parse of live hooked transcripts, delta hook writes, lighter pollers
- Session sync leaves a transcript alone while hooks feed its session live
  (active, newest event a hook's, touched within DASHBOARD_SYNC_LIVE_HOOK_MS,
  default 5 min) and catches it up once quiet; a hook-created session (which
  importSession skips anyway) is only snapshotted, never parsed.
- Hook writer keeps a per-transcript mark (applied after commit): an
  unchanged TranscriptCache result skips token/compaction/API-error/turn
  writes, a grown one walks only the entries after the last one handled.
- Codex usage: one stamp query per pass instead of one row per journal;
  between full passes (first + every 5 min) only the newest day folders and
  journals written in the last hour are statted; fork parents resolved from
  the table or a full walk.
- Cursor/Antigravity polls back off to 60 s after idle passes
  (server/lib/backoff-poll.js); lane sync runs only while another dashboard
  shares the data dir (checked every 30 s).

/**
* @file Tests server/lib/codex-usage.js — Codex sessions and token usage read
* from rollout journals: the token mapping (input includes cached, output
* includes reasoning), duplicate totals, a mid-session model switch, a fork's
* copied history skipped, a sub-agent thread folded into its root session,
* incremental reads, a deleted session not resurrected, and a Claude row never
* touched; a remote source's mirror read with its own source tag, home and
* activity window; a folder the user ignores never written. CODEX_HOME and the
* DB live in a temp dir.
