fix: improve package management and screen status

- Fix issues in package installation and removal across
different platforms (Ubuntu, macOS, Alpine, Arch).
- Improve error handling and add sudo support where
necessary.
- Enhance screen status check to accurately reflect
process activity.
- Address minor bugs in `db.v`, `done.v`, and
`net_test.v`.
- Correct minor inconsistencies in package names.
