Improve module compile checks

[cristianrgreco]

Summary

• Update check-compiles to use TypeScript build mode across packages/testcontainers and packages/modules/*, so referenced package declarations are built before dependent modules compile.
• Update AGENTS.md to require npm run check-compiles when touching packages/testcontainers APIs consumed by modules.

Verification

• npm run check-compiles

Test results

• npm run check-compiles passed.

Semver impact

• Patch. This is a maintenance-only change to repository checks and contributor instructions; it does not change runtime behavior or public package APIs.
