Build Cobble project structure from the handoff

- Remove the preset document suite (letters, emails, invoices, quotes, PDF generation, line items) with its routes, API handlers and tables - Rebrand to Cobble: site data, Lato, handoff design tokens (light and dark) in main.css, brand assets in public/brand, ember stone logo and regenerated favicons - Add bots, bot_messages, bot_tasks and bot_task_steps tables, regenerate DB types (BUN_SQLITE_COBBLE_*) and add a sample crew seed (seed:bots) - Add the chat shell at /admin/bots: rail with pinned coordinator and user popover, bottom-anchored conversation with composer, working-on panel, and a send-message API scoped to the session user - Add BotStone and Wordmark components, crew status and relative time utils with tests, and update AGENTS.md Co-Authored-By: Claude Opus 5.5 <[email protected]>
