Release version 0.12.0

• feat(pet): meet your new desktop companion — a Codex-compatible pet that lives on your desktop, reacts to chat events with rich animations, and is fully managed from Appearance Settings.
• feat(pet): browse, install, and switch pet characters from the new built-in marketplace with one click.
• feat(pet): hover to get a wave, drag to flip the pet's facing direction, and enjoy looped idle and event animations — all without ever stealing keyboard focus from what you're working on.
• feat(pet): right-click the pet for a native menu to control it without opening Settings.
• feat(chat): see exactly how long the assistant took to reply, right in the message footer.
• feat(codex): images generated by Codex now render inline as first-class content blocks instead of plain links.
• feat(window): closing the main window keeps codeg running in the tray so background sessions and notifications continue uninterrupted; quit fully from the tray menu.
• feat(window): on macOS, the tray icon now uses a monochrome template that adapts to light and dark menu bars.
• feat(window): the Settings window now stays attached to its owner, so it can no longer get lost behind other windows.
• fix(updater): the in-app updater reports the actual installed version when running in server mode, so update prompts are accurate.
• fix(acp): agents that run git commands now pick up your local git credential helper, so private repositories work without re-authenticating.
• chore(acp): bump Codex ACP to 0.14.0.
• style(conversations): tiled conversation panels can shrink to 24rem, fitting more sessions side-by-side on smaller screens.
• i18n(chat): grouped tool runs (read/edit) now show call counts instead of file counts, reflecting actual activity more accurately.
