Jan Piotrowski f9734c7e67 feat: extract commands from TUI to commands module
- adjust discord max message length to 2000 (the actual limit)
- /install-skill will fallback to searching EvoSkills repository if path not found to allow for installing skills from channels
- remove discord config tests (it asserted @dataclass behaviour)
