fix: remove auth gate from onboarding launch

[marcusquinn]

Summary

• Removes the auth.json check that was blocking the onboarding launch when no auth was configured
• OpenCode handles authentication interactively — it doesn't need pre-auth to launch
• Restores the original auto-launch behavior: always offer to launch, let OpenCode handle auth
• Model detection still works as a nice-to-have (picks Claude/Gemini if auth exists)

What was wrong

PR #698 added an auth check that showed "run opencode auth login" instead of launching OpenCode when no auth.json existed. This was incorrect — OpenCode prompts for auth on first run.

Net result (PR #698 + this PR)

The good parts of #698 are preserved:

• Commands generation decoupled from find_opencode_config guard (commands work without opencode.json)
• update_opencode_config runs after setup_opencode_cli in interactive path

Only the incorrect auth gate is removed.

Summary by CodeRabbit

• Chores
  • Simplified onboarding workflow to consistently present setup options to users.
  • Implemented automatic AI model selection during initialization based on available authentication providers.

Walkthrough

The setup.sh script now unconditionally offers OpenCode onboarding and dynamically selects a model based on detected authentication providers in auth.json. The conditional gating that checked for existing authentication is removed, replaced with inline provider detection that populates an optional --model parameter for the onboarding command.

Changes

Cohort / File(s)	Summary
OpenCode Onboarding Logic Simplification setup.sh	Removed conditional authentication check before onboarding prompt. Added inline auth provider detection from auth.json to dynamically select model (anthropic/claude-sonnet-4-5 or google/gemini-2.5-flash). Constructs onboarding command with optional --model parameter based on available provider. Net reduction of 18 lines.

Poem

Scripts refactored, logic lean—
