Tianyi Cui f1dac1b1ed fix(session-persistence-sqlite): defer crash-tail repair to append; fix all-tail materialized flag; persist schema version (review #35) ...

- load() no longer DELETEs the crash tail — it stays non-mutating w.r.t.
  the event log and records a repair point (repairFrom). The next append
  runs the DELETE inside its own transaction before inserting. This makes
  the SQLite backend honor the SAME public contract as JSONL (load returns
  the committed prefix; the subsequent append performs the one-time
  physical truncation-repair), instead of mutating during load.

- All-tail load: when the discarded crash tail was the session's only
  committed content (committed.length === 0), the metadata row still read
  materialized = 1 from the prior append, so has()/list() reported a
  session load() had just emptied. load() now flips the row's materialized
  flag to 0 (metadata only — the orphaned event rows are still removed by
  the deferred repair), so has()/list() are immediately consistent.

- Schema version: openDatabase now stores SCHEMA_VERSION in PRAGMA
  user_version on a fresh database and rejects opening one whose
  user_version is newer than this build supports, protecting against a
  future incompatible layout.

Regression tests: load is non-mutating (tail rows survive until the next
append), all-tail load makes has()/list() false, and a newer-schema
database is rejected on open.
