Module sql_bridge 

SqlAccess trait bridge to ConnectionPool. SqlAccess bridge: connects ConnectionPool to khive_storage::SqlAccess.

Two modes:

• File-backed: ordinary reads check out pooled readers per operation. The only standalone-reader exception is an explicitly admitted multi-call deferred read transaction; standalone writer handles remain capped at one. Cross-statement write atomicity goes through atomic_unit, which drives a single registered raw transaction span rather than a caller-held per-tx connection.
• Memory: Uses pool-backed approach (acquire pool connection per-query inside spawn_blocking).
