v0.3.4

Fixed

• Sync no longer slows down as the warehouse grows. The full-text triggers
  located a row's index entry with DELETE ... WHERE <key> = ... on an
  UNINDEXED FTS5 column, which scans the whole FTS table, so every upsert of a
  PR, issue or comment cost a full scan. At 259k issue comments one sync all
  ran past launchd's two-hour limit. Migration 8 rebuilds the four FTS tables
  keyed by the source rowid, makes the triggers delete by rowid, and skips the
  update trigger when no indexed column changed. On an 8.5 GB warehouse a
  comment upsert now takes about 8 ms, and the one-time rebuild took 6m49s.
  The rebuild runs when the first command opens the warehouse after the
  upgrade, so expect that first sync or search to take minutes on a large
  warehouse.
