[#98] Clean up entrypoint CLI

[orecham]

Notes for Reviewer

Refactoring of commands.rs:

• add abstraction to make logic testable
• remove duplicate code
• utilize anyhow since errors only require printing, no unique error handling
• fix bug where args were not forwarded to subcommands
• remove need for --dev flag
  • dev builds will instead have their build type appended (e.g. foo-debug or foo-release)
    • utilize cargo_metadata to more reliably determine the target dir to search for dev builds
