Orbit Pi 0.2.11

Added

• The new-task page's background is now a living ordered-dither field instead of a
  static dot grid. An 8×8 Bayer screen of four dot sizes over a soft density field
  covers the page edge to edge — densest in a band behind the composer, calmer but never
  empty at the window's borders and corners — and drifts slowly enough that dots cross
  their thresholds a few at a time, so
  the page breathes instead of strobing. It reads the same dither language the photo
  backdrop already speaks, costs no asset, follows the palette, and freezes under
  Reduce Motion. A configured background image still replaces it.
• The app monogram is screened into that field. Its mask is sampled from the mark the
  binary already ships (app-icon.png) rather than redrawn, so the backdrop cannot drift
  from the icon and a cargo run build never grows the Alpha pill; the glyphs hold a quiet
  density at rest and a soft band of light crosses them about every twenty seconds, filling
  each letter with the largest dot in turn. A window too small to hold the mark drops it.
• The terminal panel is tabbed. ⌘T opens another shell in the current
  workspace, ⌘W closes the active one (the panel closes with its last tab), and
  ⌘⇧] / ⌘⇧[ step between tabs — all scoped to the terminal, so Ctrl+Tab still
  reaches the shell and session cycling is untouched elsewhere. Where Ctrl+W and
  Ctrl+T belong to the shell (Windows, Linux), the same actions take
  Ctrl+Shift+W / Ctrl+Shift+T instead. A background
  tab keeps its PTY alive: a build left running in one tab keeps running while
  you work in another. Switching sessions no longer kills the shells either;
  new tabs follow the active workspace, existing ones stay where they are.
• Each tab carries its login-shell profile mark (zsh, bash, fish — the Simple
  Icons shell logos, CC0), with the shell name and start directory on hover.
  The panel also gained a proper resize handle above the tab strip, so the
  header row belongs to the tabs instead of doubling as a drag target.

Fixed

• Sending a prompt now shows the run immediately. The composer used to stay on
  Send and the transcript stayed silent until pi's agent_start and the
  first streamed token — on a slow provider, or a pi that was still booting,
  the send looked dropped. The turn is now in flight from the moment you press
  Enter: the composer flips to Stop, the transcript shows the live
  “Working for…” row (its clock starting at the send), and a second Enter
  queues a follow-up instead of racing a second prompt. A prompt pi rejects
  unwinds that state, so nothing is left spinning.
• macOS: closing the window no longer strands the app. The Dock icon kept its
  running dot but a click did nothing — the reopen request macOS sends to a
  windowless app had no handler, so only a full quit brought a window back.
  Clicking the Dock icon (or the app's Dock tile) now opens the window again,
  on the session that was still open — the shell, the pi process behind it,
  and any stream that kept running while the window was closed all survive the
  close. The heartbeat runs on the app rather than the window, so a run that
  settles with no window open still posts its notification.
