v3.6.3

### ✨ New Features

- **feat(docs):** integrate multi-page documentation into OmniRoute dashboard (#1969)
- **feat(settings):** add request body limit setting (#1968)
- **feat(auth):** add Gemini CLI OAuth client secret default (#1974)
- **feat(models):** expose models.dev context windows in /v1/models (#1972)
- **fix(db):** resolve legacy encryption fallback causing re-encryption loops (#1941)
- **fix(auth):** fix Codex assistant final_answer response sanitization (#1965)

- **feat(providers):** Implement Image Generation and Editing capabilities for ChatGPT Web, including in-band chat image generation and caching (#1606).
- **feat(ui):** Integrate OpenCode Zen/Go API tool logo SVG and polish API key copy-to-clipboard interactions (#1607).

- **feat(providers):** Integrate AgentRouter as a new OpenAI-compatible passthrough provider with $200 free credits via sign-up (Issue #1572).
- **feat(ui):** Implement on-demand per-model testing in the provider dashboard, allowing single-token diagnostic checks without triggering rate-limits (Issue #1532).

- **OpenAI-Compatible Loose Validation:** Empty API keys can now be naturally submitted and saved for any `openai-compatible-*` providers (e.g. Pollinations, localized routes) directly in the UI instead of blocking save actions (#1152)
- **Cloudflare Configuration:** Updated the provider schema and UI integration for Cloudflare AI to officially expose and support the backend `accountId` field securely without overrides (#1150)

### 🐛 Bug Fixes

- **fix(mitm):** Compile MITM utilities as NodeNext ESM during prepublish, copy the CommonJS MITM server into the standalone artifact, and resolve MITM data paths without relying on Next.js aliases in packaged runtime.
- **fix(build):** Move the local `.tmp/wine32` Wine prefix out of the isolated Next.js build path so Windows Electron packaging artifacts cannot trigger `EACCES` scans during Node 24 builds.
- **fix(build):** Copy the `wreq-js` native runtime directory into the isolated Next.js standalone output so packaged Playwright/E2E starts can load the instrumentation hook on Linux.
- **fix(api):** Validate the Codex Responses websocket bridge and `/v1/batches` JSON payloads with Zod before use, keeping `request.json()` route validation green and returning explicit 400 responses for invalid bodies.
- **fix(providers):** Add explicit typing to provider alias and category helpers so the strict `typecheck:noimplicit:core` CI gate passes.
- **fix(ui):** Keep the upstream proxy provider detail page labeled with a fallback "Managed via Upstream Proxy Settings" management surface when translations are unavailable.
- **fix(electron):** Harden the production desktop CSP by removing `unsafe-eval` outside development and adding object, base URI, form action, frame ancestor, and worker restrictions.
- **fix(cli):** Replace shell-interpolated setup and privileged command execution paths with argument-based `spawn`/`execFile` helpers for database setup, Tailscale sudo commands, MITM DNS edits, and certificate install/uninstall flows.
- **fix(ui):** Keep provider icons resilient by using direct `@lobehub/icons` components first, then local PNG/SVG fallbacks, avoiding the `@lobehub/ui` peer runtime in the dashboard.

- **Vertex JSON Validation Crash:** Prevented `invalid character in header` crashes inside the `/validate` endpoint by creating a native authentication parser that correctly handles Google Identity Service Account JSON flows prior to pinging endpoints (#1153)
- **Extraneous Payload Rejection:** Globally prevented upstream `400 Bad Request` execution crashes by stripping the non-standard `prompt_cache_retention` attribute forcibly attached by Cursor/Cline IDE engines when targeting strict OpenAI/Anthropic routes (#1154)
- **Reasoning Content Drop:** Prevented pure reasoning packets, common in advanced fallback models like DeepSeek, from being aborted mid-stream by explicitly adjusting the `Empty Content (502)` circuit breakers to acknowledge `reasoning_content` states as valid (#1155)
- **Desktop Windows Build Crash:** Fixed `better_sqlite3.node is not a valid Win32 application` preventing OmniRoute Desktop from launching on Windows by properly removing the ABI-mismatched sqlite cache from Next.js standalone and falling back to the cross-compiled Electron equivalent during packager build steps (#1163)
- **Login Visual Security:** Removed the raw fallback hash dump that artificially rendered underneath the login modal in Docker instances missing `OMNIROUTE_API_KEY_BASE64` flags (#1148)

### 🔧 Maintenance & Dependencies

- **Dependabot Updates:** Safely bumped GitHub Actions `docker/build-push-action` to v7 and `actions/download-artifact` to v8
- **Electron Updates:** Upgraded desktop wrapper core to Electron `41.2.0` and `electron-builder` to `26.8.1`, incorporating essential V8/Chromium security patches
- **NPM Package Groups:** Updated `production` and `development` NPM groups to securely handle minor audit warnings and keep toolchains modern
- **CI/CD Reliability:** Fixed persistent `Snyk` token-absence failures on automated pull requests by appropriately bypassing on dependabot actions
