* ci: limit test threads to 16 to prevent postgres pool exhaustion
Running all tests with unlimited parallelism exhausts postgres
max_connections (default 100), causing sqlx::test databases to fail
setup and producing spurious RowNotFound errors.

* fix: CI ruby env vars and mysql test binary coercion
- Ruby executor reads RUBY_BUNDLE_PATH and RUBY_GEM_PATH but CI was
setting BUNDLE_PATH and GEM_PATH, causing "Executable bundle not
found on worker" errors.
- MySQL test CAST(CONCAT(...) AS CHAR) returns binary type when param
is bound as bytes. Use CONVERT(? USING utf8mb4) to ensure character
result type.
