feat: appbar pickers, multi-agent personas, threads, library, profile
Adds a substantial chrome layer atop the bare template: Appbar - Font-size picker (root font-size scale): S/M/L/XL - Surface picker: tints --background/--card/--popover/--sidebar/--muted/ --secondary/--accent across light + dark - Background picker: 11 atmospheric gradients (Pearl, Linen, Mist, Dawn, Seafoam, Aurora, Sunset, Meadow, Midnight, Blush, Noir) + None - Vivid foreground tokens for stronger text contrast; fixed dark-mode blue-on-blue user bubble (deeper --primary, near-white --primary-fg) Assistant route - Multi-agent personas (~/lib/agents.ts): Atlas, Forge, Inkwell, Pilot, Cursor — each with name/role/sub-prompt; per-thread persona; agent picker with avatar tint + handoff submenu - Conversation threads (~/lib/threads.ts): new/switch/rename/delete, auto-titling from first user message, per-thread pinned indices - Compact summarization with snapshot-based Restore that preserves pinned messages verbatim - Edit & retry the last user message, Regenerate, Continue, Show system prompt, Copy / Export Markdown, Save to Library, Compare across agents (parallel completions in a side-by-side modal) - Per-message Pin / Read aloud (Web Speech) / Edit - Voice input via Web Speech Recognition - Two-column Actions popover (UI Control + Conversation / Share / Multi-agent / Clear sections) - Status bar: connection dot + LOCAL/API/MOCK chip + host chip + context progress bar - Compactly named threads picker; New conversation - DropdownMenuItem onSelect → onClick (base-ui Menu fires onClick) Library - ~/lib/library.ts store, /library route with search + detail panel (Copy / Download / Delete) Profile - /profile route + ~/lib/profile.ts (name/email/title/bio/signature/ avatar dataURL/default agent), AppShell uses live profile for the appbar avatar; account menu now navigates to /profile Settings - Sub-sidenav (LLM / Agents / Appearance / Account / About) - Editable system prompt with reset-to-default - Agents CRUD panel - Reorganized layout UI Control - Static action catalog in the system prompt so the assistant can drive controls on routes that aren't currently mounted - Always returns to /assistant after a UI Control sequence (model- side rule + deterministic safety net) - Cursor uses click-nav over direct navigate so the virtual cursor is visibly involved - New ids tagged across the app (sidebar, settings, profile, library, assistant tools, agent handoff, thread management) Hydration - root.tsx: suppressHydrationWarning on html/body since the pre-mount script sets dark/data-bg/data-surface/data-font-scale before React Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
