Remove deprecated and redundant CLI commands

Remove deprecated and redundant CLI commands

Summary

This PR removes 13 CLI commands that were identified as deprecated, redundant, poorly documented, or experimental. The cleanup removes ~4,900 lines of code while preserving all core CLI functionality.

Commands removed:

• runtasks - deprecated in favor of configure
• recreate - redundant with delete + start sequence
• hello - onboarding command with references across multiple commands
• background - niche use case with limited documentation
• test, clipboard, envvars, connect, fu - dev-only commands behind feature flags
• writeconnectionevent, updatemodel - poorly documented internal commands
• configure-env-vars, import-ide-config, secret - user-specified removals
• Fixed duplicate start command registration

Core commands preserved: start, stop, delete, reset, login, logout, ls, shell, open, create, org, set, etc.

Review & Testing Checklist for Human

• Verify removed commands aren't used in production - Check internal scripts, documentation, CI/CD, or user-facing materials that might reference these commands
• Test new user onboarding flow - The hello command and onboarding logic was completely removed from login, ls, shell, and open commands. Ensure new users can still successfully get started
• End-to-end testing of core workflows - Test primary user journeys: login → ls → start → shell/open to ensure nothing is broken
• Check for references in other repos - Search for usage of removed commands in related repositories or documentation sites

Notes

• Build verified: CLI compiles successfully and core commands show expected help output
• Import cleanup: Removed unused imports and resolved all compilation errors
• UX changes: Replaced TypeItToMeUnskippable27 calls with simple terminal prints - behavior may differ slightly
• Session info: Requested by Alec Fong (@theFong) - Devin session

I merged improvements to the --help page that also removed broken commands. I think we can close this.
