Atrium v0.10.0 — The Cockpit, Furnished

The largest release since the cockpit foundation. The full next-era program (worktree restore resilience, status legibility, the UX calm pass, the Worktree View, and the Pro v1 bundle) plus a deep polish-and-fix pass: 6 preset themes, a command/keybinding registry with a ? cheatsheet, pin-a-pane, an Open-lazygit hatch, scrollback search, worktree Inventory triage (last-activity + dirty), a constant-identity status orb, CVD-safe agent colors, and fixes for the close button, worktree-create hang, and an atrium.toml import security gate. See the full CHANGELOG in the repo.
