Devx 314 cli onboarding changes

[smukherjee-godaddy]

Summary

Users now accept legal agreements directly in the terminal before SSO, and onboarding completes automatically in the
background after login — no browser redirect to the portal registration page required.

Changes

• src/core/onboarding.ts — Removed local callback HTTP server, waitForOnboardingCompleteEffect, and browser
  imports. Added two new effects:
  • checkOnboardingStatusEffect — POST /api/v1/onboarding/status to get current org status
  • completeOnboardingEffect — POST /api/v1/onboarding/cli to accept all agreements and submit onboarding in one
    call
• src/cli/commands/auth.ts — Updated login flow:
  • Shows ToS / Privacy Policy / Developer Agreement links before opening the browser; prompts user to press Enter
    to accept (skipped in non-interactive/CI)
  • After OAuth, checks onboarding status; if PENDING calls completeOnboardingEffect
  • Emits org_id and onboarding status in result; both steps are non-fatal
• src/core/environment.ts — Added getDevxCoreUrl with DEVX_CORE_URL env var override for local dev
• src/core/auth.ts — Token exchange now includes client_secret in request body

Test Plan

• New user → agreement prompt shown → OAuth → onboarding completes → org_id in output
• Existing ACTIVE user → same flow, returns immediately without re-onboarding
• Non-interactive (echo "" | godaddy auth login) → prompt skipped, proceeds automatically
• Re-login → already-accepted agreements handled idempotently, no error
