Add queue tables, quote SQL identifiers (v1.3.0)

- isQueue table option adds queue columns and a (status, available_at)
  index; BunSQLite.queue exposes add, claim, complete, fail and
  release_stale with atomic claims
- Set busy_timeout on connections so workers in separate processes wait
  instead of failing with SQLITE_BUSY
- Quote table and column names with backticks in generated SQL, so
  reserved words (to, order, group) work and unknown columns error
  instead of matching as string literals
- Tests for queue ops, multi-process claims and reserved-word names
