v0.3.1 — PR waves 80–85 + Docker image hygiene

Open Swarm 0.3.1

Everything since v0.3.0, landed via squash-merged PRs #80–#85, plus a Docker image hygiene fix.

Added

• Websocket chat is now functional — ASGI routing wired (swarm/asgi.py + routing; channels/daphne registered); SPA ChatPage with streaming
• SPA agent-creator + settings pages on live APIs; token-auth UX with 401 banner (#80)
• JSON Teams API /v1/teams/ wired to the SPA TeamsPage
• NOTICE file (MIT + OpenAI Swarm/openai-agents attribution); opt-in mem0 e2e harness (#85)
• uv.lock tracked — CI lock-drift check is now meaningful (#81)

Changed

• vite 5 → 8; npm audit: 0 vulnerabilities (#84)
• 18 community/agent branches absorbed: shlex command-hardening, perf optimizations, UX boxes, +20 tests (#83); all 87 historical branches now dispositioned — origin contains only main

Removed

• Wagtail marketplace + SAML IdP scaffolding (−716 lines; GitHub-topics discovery retained) (#82)

Security / hygiene

• Hardened .dockerignore — the image previously shipped the full .git history, a dev database containing auth_user password hashes, local tool state (.letta/, .claude/), and __pycache__ files embedding local filesystem paths. Rebuilt image verified leak-free and booting.

Tests: 864 passed / 0 failed. Docker: verified serving /v1/models, web UI, and OpenAI-format chat completions.
