Goose v1.32.0 ships Exa search, voice dictation, and agent mentions

Goose `v1.32.0` is a substantial release adding over 20 new features alongside a wide range of bug fixes and improvements. Highlights include an Exa AI-powered search tool, `@agent` mention support in chat, desktop notifications when a task finishes, a `/skills` command, and voice dictation via the direct-ACP pattern in goose2. Two new AI providers — Novita AI and Kimi Code (with OAuth device flow authentication) — are now available, and a Cash App extension has been added to the Extensions Library. On the bug-fix side, a ~5-second delay when opening the Switch Models panel with a local provider has been eliminated, and an idle 300ms re-render loop that could OOM the TUI has been stopped.
