Fix e2e tests and clean up debug artifacts

- Remove nested test/e2e/test/ directory (bad debug data)
- Fix run-all.sh to run VHS from repo root, preventing nested output
- Fix cursor-navigation.tape to use setup script instead of inline shell
- Add setup-cursor-test.sh for cursor navigation tests
- Regenerate all test outputs without FileNotFoundException errors
- Add debug tape/output files to .gitignore
- Remove debug.tape from test suite (for local debugging only)
