chore: drop committed junk files and ignore python caches

- remove the stray '1.2.0' file at the root, an npm install log committed by accident.
- remove the committed __pycache__/*.pyc binaries and ignore __pycache__/ and *.pyc.
- add .gitattributes marking .agent/** as vendored/documentation so GitHub stops
  reporting the repository as Python when the app is TypeScript.
