Orbit Pi v0.2.2

Hover hints now carry the shortcut: the model and thinking chips, New Task, the sidebar's Search/Usage rows, the top-bar panel toggles, the Git page tabs, and the workspace + use registry-backed tooltips ("Choose Model (⌘⇧M)"), and hovering a session row shows the ⌘1…⌘9 slot that opens it.
A single command registry now backs the keymap, the command palette, and Settings → Shortcuts, so a chord, its chip, and the action it runs can never drift apart. The palette gained Rename Session, Pin / Unpin, Clone Session, Delete Session, Choose Model (⌘⇧M), Choose Thinking Level (⌘⇧T), Review Changes (⌘⇧R), and Keyboard Shortcuts (⌘/).
Session management is number- and cycle-addressable: ⌘1…⌘9 (Ctrl+1…9) open the Nth session in the sidebar's visible order, and Ctrl+Tab / Ctrl+Shift+Tab cycle to the next or previous session. The palette also lists Next Session and Previous Session.
The Review pane is fully keyboard operable: Tab / Shift+Tab move between the workbench's focus stops, arrows walk the changed-files tree, Enter opens a file or toggles a folder, n / p jump between changed files, [ / ] jump between hunks, e / c expand or collapse every file, and Escape returns to the chat. The composer's autocomplete and the terminal keep Tab for their own use.

The Git page tabs moved from ⌘1…⌘5 to ⌘⌥1…⌘⌥5 (Ctrl+Alt+1…5) so the number keys can address sessions directly.

Orbit and orbit-rpc also probe ~/.pi/agent/bin for the pi launcher, alongside the npm/pnpm/bun home dirs they already checked. A bundled .app never inherits the shell PATH that contains it, so a pi installed there used to read as missing.
Shortcuts that were advertised but macOS-only (cmd- editor clipboard and undo, Files close, Git page tabs) now use the platform modifier, so Windows and Linux get the same keys. The ⌘. abort chord was dead — gpui names the key ., not period — and now fires.
Compaction and branch summaries now appear in the transcript as boundary cards: Compaction — Compacted from 150K tokens (click to expand the summary) and Branch summary. A successful compaction also re-reads pi's compacted context right away, so the summarized history is replaced by the summary the moment it lands instead of lingering until the session is reopened.
