feat(ui): UI improvements, restart fix, theme picker, and model list

[cryptiklemur]

Summary

Major batch of UI improvements, bug fixes, and new features:

Bug Fixes

• Restart Server now works — onRestart callback was never wired through server.js to project.js, causing "Restart not supported" error. Added the two missing lines to extract and pass the callback.
• Restart error handling — Added try/catch in daemon.js spawnAndRestart() to broadcast error toast on failure, and reset the restart button on reconnect.

New Features

• AMOLED Dark theme — True black (#000000) background theme for OLED displays, added as lib/themes/amoled.json
• Appearance section in Server Settings — New "Appearance" nav item with full theme picker embedded in settings (12 dark + 11 light themes with color swatches)
• Per-variant theme memory — Dark and light theme selections are stored separately (clay-skin-dark / clay-skin-light), so toggling remembers your chosen theme for each mode
• Settings button in user island — Gear icon next to theme toggle opens Server Settings directly
• Expanded model list — Supplements SDK's supportedModels() with known models (Opus, Claude Sonnet 4, Claude Opus 4, Claude 3.5 Sonnet, Claude 3.5 Haiku) so all models are always visible
• Full-width chat toggle — Option in profile popover to use full viewport width for messages
• Right-click context menu on sidebar icons — Now shows full project menu (Settings, Share, Remove) instead of just "Set Icon"
• Session ID input in Resume modal — Paste a session ID to import/resume a specific CLI session
• Session ID badge — CLI session list items show truncated session ID for identification
• Mobile swipe gesture — Swipe left anywhere to open the project list on mobile

UI Changes

• Removed top bar — Theme toggle moved to user island, version moved to user island, status pills moved to header area

• Verify settings gear button in user island opens Server Settings overlay
• Verify model list shows all 8 models (Default, Sonnet, Haiku, Opus, Claude Sonnet 4, Claude Opus 4, Claude 3.5 Sonnet, Claude 3.5 Haiku)
• Verify full-width chat toggle in profile popover works
• Verify right-click on sidebar project icons shows full context menu
• Verify session ID input in Resume modal allows importing by ID
• Verify mobile swipe-left opens project list

hey, thanks for putting this together. i do have to close this one though. per the contributing guidelines, i don't accept feature PRs. the project has a specific direction and all features are written by me to keep things consistent.

the restart bug fix looks solid though. if you can pull that out into a separate PR, i'll review and merge it.

there are some good ideas in here and i'll consider them for future updates. if you want to track those, feel free to open individual issues so they can be discussed.

appreciate it.
