glm-5.3-flash 908fb5d2dd feat(engines): the sqlite kv engine — the default engine, first SQL-backed (wave 3) ...

Implements the sqlite kv-tier engine per ADR-003/007/010 §1 behind
feature `sqlite` (default-on): the B5 row shape (key BLOB PK / value
BLOB / size INTEGER NOT NULL), INSERT OR IGNORE CAS first-writer-wins
on both put forms, the EXISTS has probe, the materializing cursor body
with len() from the size column, the degenerate in-memory stage with
both hygiene forms, the indexed-column size probe (plan-tested), the
no-tables-yet virgin-store read tolerance (tested against a tableless
database file), WAL + synchronous=NORMAL verified at open, prepare_cached
discipline, and every rusqlite operation in spawn_blocking under the
recorded single-connection posture.

Task: tasks/engine-sqlite.md (status: completed). The engine-state
window family and store construction remain in their own tasks.

Verification:
- cargo test — 58 pass (11 new sqlite in-module tests)
- cargo clippy --all-targets -- -D warnings — clean
- cargo fmt --check — clean
- cargo check --no-default-features — green
