dartapi_db 0.0.8

A light weight Database helper wrapper for dartapi.

0.0.8

• Add DbTransaction abstract class for transaction-scoped query sessions
• Add DartApiDB.transaction<T>(callback) — runs callback in a DB transaction; commits on success, rolls back on exception
  • PostgreSQL: uses Pool.runTx() (native transaction session)
  • MySQL: acquires a dedicated connection via pool.withConnection() with START TRANSACTION / COMMIT / ROLLBACK
  • SQLite: uses BEGIN / COMMIT / ROLLBACK on the same connection
• Add SqliteDatabase driver — full DartApiDB implementation backed by sqlite3
• Add DbType.sqlite enum value
• Add DbConfig.sqlite(String path) convenience constructor; use ':memory:' for in-memory databases
• Add MigrationRunner — Flyway-style SQL migration runner that tracks applied migrations in _dartapi_migrations
• Add 19 tests for SQLite and MigrationRunner (no server required)

0.0.7

• Add connection pooling for PostgreSQL (via Pool.withEndpoints) and MySQL (via MySQLConnectionPool)
• Add PoolConfig class with maxConnections, minConnections, connectionTimeout, and idleTimeout
• Add optional poolConfig field to DbConfig — backward compatible, defaults to PoolConfig() when omitted

0.0.6

• Fix MySqlDatabase.update() parameter collision when the same column appears in both SET and WHERE clauses (WHERE params now use w_ prefix internally)
