fix(ci): skip integration tests and configure linter

- Add .golangci.yml to configure golangci-lint
- Skip integration tests in CI that require external resources
- Add CI env var to test run
- Rename RouterAgent -> Classifier (better naming)
- Update .gitignore for docs/plans/ temporary directory
