fix(ci): resolve lint errors and test failures

- Fix errcheck: handle watcher.Close() and Set() return values
- Fix unparam: remove always-nil error from NewActivityWatcher
- Fix unparam: remove unused sinceTime param, delete dead code
- Fix version mismatch: update MCP __init__.py to 0.48.0
- Fix routing tests: change CWD so routing can find town root
