refactor: convert to bun-workspaces monorepo (desktop/ + www/)
- Move the Tauri app (React frontend + Rust backend) into desktop/ via
git mv — configs unchanged (relative paths: tauri.conf.json, vite.config.ts)
- Root package.json becomes a private bun workspace container with
orchestration scripts; desktop package renamed gridline-desktop
- Scaffold www/ with Astro 7 + Tailwind v4 (hand-wired vite plugin,
static output, ready for Dokploy)
- Update release.yml for the new layout: projectPath: desktop,
desktop/src-tauri resource paths, rust-cache workspace path
- Update README + AGENTS.md structure trees and dev commands
- Verified: vitest (1074), cargo test (354), desktop build, tauri dev
(window launches), tauri build (dmg + app bundles), Astro build
