- esbuild alias fixed in the session/sysinfo/sftp test commands (they
could not build at all), .sftp-svc.mjs build documented, real
connection-stability assertions
- tests/build-bundles.cjs builds every bundle fresh; npm test runs the
seven offline suites; esbuild pinned in devDependencies
- remove the assertion-less .exact-inline.mjs; ignore/clean test temp dirs
