feat: expose native driver failures through public modules

[medz]

Refs #516

Driver exceptions already propagated unchanged, but ORM consumers could not name them through the public driver modules. Re-export PostgreSQL's native error types and SQLite's exception, primary-code constants and extended-code constants through each module's implementation and explicit public entrypoint.

Applications can catch native failures outside a transaction using only ORM public imports. SQLSTATE, severity, table/constraint metadata and SQLite result codes retain their native meanings. Expected registration conflicts still use createIfAbsent with an explicit target. Standard TimeoutException stays in dart:async; no wrapper, error remapping or retry behavior is added.

Validation: twenty live SQLite/PostgreSQL business tests pass and analysis is clean. Two new cases provoke unique and missing-parent failures, check the actual public types/codes, verify an earlier write rolls back and confirm subsequent root queries remain usable. The independent archive consumer now compiles all eight native symbols from ORM-only dependencies and repeats those real rollback checks. Model generation and reviewed migration definitions/fingerprints are unchanged.
