Send synthetic session notifications when background processes finish, fail, stop, or terminate so the originating agent can react without polling. Hide synthetic text-only prompts from the UI stream so operational notifications stay out of the visible transcript.
## Summary
- add server-backed speech capabilities and transcription endpoints plus
UI settings for speech configuration
- add push-to-talk prompt voice input with microphone controls,
transcription insertion, and browser capability gating
- keep prompt controls aligned by restoring right-side nav placement and
moving the mic beside the expand control
### Summary of Improvements
This PR replaces the custom `IntersectionObserver`-based virtualization
with the `virtua` library to significantly improve rendering performance
and UI responsiveness.
### 🚀 Performance Results
Verified using `session-performance.test.ts`:
- **Rendering**: 2000 messages rendered in **16.90ms**.
- **Huge Conversation**: 10,000 messages processed in **0.80ms**.
- **Session Switching**: Average switch time reduced to **0.58ms**
(virtually zero lag).
### 🛠️ Key Changes
- **Virtualized Message Stream**: Integrated `virtua/solid` for
efficient windowing and automatic scroll compensation.
- **Floating Scroll Controls**: Applied `position: absolute` and
`pointer-events: none` to the list controls to ensure
scroll-to-top/bottom buttons float correctly over the message area
without blocking interactions.
- **Package Synchronization**: Updated `virtua` and SDK dependencies,
with a fully synchronized `package-lock.json` for stable builds.
### 🎥 UI Verification
https://github.com/user-attachments/assets/24e483a3-8be6-4ac4-a431-d719f2015f4e
- **Smooth Scrolling**: Verified that rendering gaps are eliminated
during fast scrolls.
- **Position Retention**: Scroll positions are preserved when switching
between sessions.
> [!NOTE]
> Detailed performance gains and layout fixes are isolated to the
`virtua` implementation and core package updates, following the
requested cleanup.

Adds a dispose instance action to the instance info view, POSTing to /instance/dispose and rehydrating per-instance stores; also handles server.instance.disposed events and adds danger button styling.
Add generic /api/storage config/state endpoints with merge-patch, migrate legacy YAML/JSON layout, and update UI/server to read and write owner-scoped settings. Replace config SSE events and drop /api/config routes.
Adds cookie-based login with a bootstrap token flow for desktop apps, secures OpenCode instance traffic with per-instance Basic auth, and updates UI/plugin clients to use credentials.
- Add platform detection (Electron vs Web) for expand behavior
- Electron: 3-state (normal → 50% → 80%) with double-click
- Web/Mobile: 2-state (normal → expanded) with instant single tap
- Implement fixed 15-line height for web/mobile (360px, capped)
- Add orientation-aware height calculation (landscape vs portrait)
- Remove tooltip on web/mobile, keep for Electron desktop
- Add responsive placeholder text to prevent overlap on mobile
- Desktop: "Type your message, @file, @agent, or paste images and text..."
- Mobile (≤640px): "Type message, @file, @agent..."
- Delete dev-docs/expand-chat-input.md per upstream feedback
Addresses PR feedback to simplify from 3-state to 2-state for web/mobile
while maintaining rich desktop experience in Electron app.
