Quarters 0.7.0

• Four more coding agents (#1): Amp, Goose, Qwen Code and Cursor CLI, twelve
  in all. Each starts, continues the last conversation (⇧C) and, where it
  has a switch, skips its permission prompts.
• quarters --version (#4): which Quarters this is, e.g. Quarters 0.7.0 (linux/amd64, server), for the server with no window and for bug reports.
• The light theme reads better (#3): muted text, yellow, green, the accent
  and red are darker, to WCAG AA contrast (4.5:1) on every light surface.
• Keyboard shortcuts work in a browser too (#5). A browser has no menus,
  so the page listens for the same keys. On Linux and Windows, Alt stands
  in for ⌘ (Alt+P, Alt+Shift+P, Ctrl+Alt+T) and every label says so. On a
  Mac, Chrome keeps ⌘T, ⌘W and ⇧⌘[ ] for its own tabs: add ⌃ (⌃⌘T).
• The status bar shows the keys for what's in front of you: splitting in a
  shell, moving between panes in a split, ⌘S in a file, moving and opening
  in the projects list.
• Keep awake, from the cup in the title bar: keep the Mac (or the server)
  awake for 30 minutes to 24 hours or until you stop it, whatever it's
  doing. The same menu switches the Keep awake setting (only while agents
  work).
• A pill beside the version: red "update available" when a newer release
  is out, grey "up to date" when not. A click says how to update: Homebrew
  or the download, for the Mac app or the server. Quarters asks GitHub at
  most every six hours.
• Add project, Settings, the theme (system, light, dark) and, in a
  browser, alerts and sign out moved to the title bar beside the panel
  buttons. On a phone they stay at the foot of the projects drawer.
• Tips are always there: one line at the bottom right, the next one every
  two minutes (› shows it now), the keys you haven't used first. They no
  longer stop after a week or three a day, and there's no switch to turn
  them off.
• In a browser, Add project asks for the folder's path instead of offering
  a Browse… button that can't open the machine's folder picker.
