fix(release): v3.0.6 — proxy context, playground selector, CI fix

- Fix: Limits usage fetch wraps BOTH token refresh and usage call inside proxy context (fixes SOCKS5 Codex accounts)
- Fix: CI integration test v1/models gracefully handles empty models list
- Fix: Settings proxy test button results now render with priority over health data
- Feat: Playground account selector dropdown for testing specific connections
- Merge: PR #623 LongCat API base URL path correction

+## [3.0.6] — 2026-03-25
+
+### 🐛 Bug Fixes
+
+- **Limits/Proxy:** Fixed Codex limit fetching for accounts behind SOCKS5 proxies — token refresh now runs inside proxy context
+- **CI:** Fixed integration test `v1/models` assertion failure in CI environments without provider connections
+- **Settings:** Proxy test button now shows success/failure results immediately (previously hidden behind health data)
+
+### ✨ New Features
+
+- **Playground:** Added Account selector dropdown — test specific connections individually when a provider has multiple accounts
+
+### 🔧 Maintenance
+
+- Merged PR #623 — LongCat API base URL path correction
