Summary

Promotes the jOOQ smoke prototype into libsql-jdbc as a Failsafe integration test.

• JooqIT drives the in-tree driver through jOOQ: CRUD, insert/update/delete RETURNING, JDBC batch, transaction rollback, and runtime code generation with GenerationTool.
• JooqSqldSupport starts the pinned sqld Testcontainer and creates the schema over Hrana, so a broken metadata path cannot hide tables from code generation.
• Code generation runs at test time, so there is no build-time database dependency and no generated sources checked in.
• Two jOOQ/driver gaps are pinned as explicit tests:
  • auto-commit generated identities are unavailable because jOOQ reads _rowid_ = last_insert_rowid() on a fresh Hrana stream;
  • SQLite (libSQL) is not auto-detected as SQLDialect.SQLITE.
• Test-only dependencies: jOOQ 3.21.9, Testcontainers, and Failsafe *IT wiring. mvn test stays unit-only.
• The module copies the shared Docker config into target/docker-config and sets DOCKER_CONFIG for Failsafe, so sandboxed runs work without a shell override.

Test plan

• ./mvnw -pl libsql-jdbc -am -Dit.test=JooqIT verify — 7 tests pass
• ./mvnw spotless:check
• ./mvnw clean verify — all modules pass (jOOQ 7, integration tests 192, conformance 271)
