First production-ready ADK release (v1.0)

[tomkis]

Goal

Ship a production-ready v1.0 release where the full local development workflow works end-to-end: platform starts, agents autoregister, CLI commands work, auth is solid, and CI gates are green.

Acceptance Criteria

Platform Lifecycle

• adk platform start provisions VM and all services reliably
• adk platform stop / adk platform delete clean up correctly

Agent Autoregistration

• Agent self-registration via Server.serve(self_registration=True) works end-to-end
• Provider creation and update (retry/backoff) succeeds against local platform
• Built-in agents (chat, rag, canvas, form) register on startup
• adk agent list reflects registered agents
• adk agent add / adk agent remove work for custom agents

CLI

• All command groups functional: agent, platform, server, model, connector, build, ui, self
• adk self version / adk self upgrade work
• adk build produces valid agent images
• adk ui launches web interface

Local Auth

• adk server login with resource owner password grant (admin:admin) works
• Token storage/refresh in ~/.kagenti/auth.json works
• Expired tokens auto-refresh transparently
• adk server logout cleans up session properly
• All authenticated CLI commands work with stored tokens

CI

• mise run check passes (license headers, version consistency, formatting, linting)
• mise run test passes (unit)
• mise run adk-server:test:e2e passes
• mise run adk-server:test:e2e-examples passes
• mise run adk-server:test:integration passes
• Release workflow (release.yml) successfully builds and publishes images on tag
• Version files are consistent across all packages

Docs & Polish

• README reflects current state
• Installation instructions are accurate and tested
• Known limitations documented
