AI-Proxy Desktop 0.2.9

AI-Proxy Desktop 0.2.9 — the first-class DVT gateway (plus the Clients revamp)

Gateway hardening (every finding from the DVT integration, fixed + regression-locked):

• System role honored everywhere — Claude-routed requests fold system content into the first user turn (their harness used to silently discard it); Gemini untouched. Your agent's grounding always reaches the model.
• Truthful /v1/models — retired ids pruned/remapped (2 newly-dead Anthropic ids added); an explicit unknown model now fails fast with OpenAI-shaped 404 model_not_found; an omitted model always completes on a live default.
• Clean error contract — every error leaves in OpenAI shape with correct status + actionable message (auth_unavailable → 503 + Retry-After). Sampling params a model rejects (temperature on newest Claude) are dropped & retried by the gateway.
• GET /health — token-free, key-free: {status, default_model, providers:{claude|gemini|openai|ollama: ok|cooldown|no_auth}}.
• Service supervision — ai-proxy run (foreground), ai-proxy service-install (launchd auto-start + auto-restart).
• Regression suite: scripts/regress.sh — 9/9 (system role, model sweep, param-drop, 404, tool round-trip, concurrent isolation, /health).

Connect Clients revamp: 38 clients with logos in 6 categories, installed-client detection, 12 battle-tested config writers with backup/Undo — DVT featured first-class (writes ~/.dvt/ai_keys.yml, byte-identical undo).
