feat(mysql): native SQL execution — fix #41 type decoding, in-process restore, .sql open-with (#42)

Fixes #41. MySQL columns now decode by their declared type instead of a blind try_get chain, so every non-string type (integers, DECIMAL, BIT, YEAR, DATE/TIME/DATETIME/TIMESTAMP) renders its value instead of NULL. MySQL restore runs in-process over the sqlx driver (no bundled MariaDB client, so MySQL 8 caching_sha2_password works) and the Clean toggle is implemented. .sql files can be opened with Gridline from the OS file manager. Verified: cargo test --lib 442 passed / 0 failed; bun run test 133 files / 1151 tests exit 0; tsc clean; both live MySQL 8 integration tests pass with the bundled CLI hidden.
