Live ingestion. Sessions are now ingested incrementally during the session
instead of only at SessionEnd, so a Claude Code crash can no longer wipe an
in-progress session's events from the index.

Added

• Stop hook + longhand ingest-live command. Fires once per assistant
  turn. Tail-reads new bytes from the transcript JSONL and upserts new
  events into SQLite. Skips heavy analysis (episodes, segments, embeddings,
  project inference) — those still run at SessionEnd. The events table
  stays current within seconds of each turn, so an editor crash, a kernel
  panic, or a stuck SessionEnd subprocess no longer means lost work.
  longhand hook install now installs both SessionEnd and Stop in one go.
• Plan history is now first-class. Every Write/Edit to a
  ~/.claude/plans/*.md file is captured as an event. The new
  plans_index SQL view (longhand plans list / mcp_longhand_list_plans)
  exposes them in chronological order. Pair with replay_file to
  reconstruct an early version of a plan that was later overwritten —
  previously, only the final plan was visible because the file on disk
  had been overwritten by the time SessionEnd fired.
• longhand schedule install-reconciler writes a launchd job
  (macOS) that runs longhand reconcile --fix every 30 minutes.
  Belt-and-suspenders for hard crashes that take down both hooks. Opt-in;
  longhand doctor flags it when missing.
• MCP tool list_plans for the Claude-side view of plan history.

Changed

• SQLite WAL mode enabled at first connect. Cuts hook latency under
  contention from worst-case 5s (busy_timeout) to ~10ms. Single-user DB,
  safe.
• longhand hook uninstall now also removes the Stop hook.
• longhand doctor has new rows for Stop hook and Reconciler job.

Schema

• Migration v5: adds last_offset column to ingestion_log (live cursor
  separate from file_size, which still tracks last-full-ingest size).
  Backfill: existing rows get last_offset = file_size. Adds
  plans_index view over events.

Tests

• 11 new tests covering: stdin contract, offset advance, partial-line
  handling, lock contention, plans_index view, migration v5,
  live → SessionEnd composition, episodes-skipped invariant.
• 222 tests passing (was 211).
