feat: replace Aider/Crush with Goose as local model driver

Goose (block/goose) actually executes tools with local Ollama models.
Rust binary, native Ollama provider, 33.7k stars.

- shellforge run goose "prompt" — headless with --no-session
- Setup wizard: brew install --cask block-goose
- Status page: shows Goose
- Site: updated everywhere
- Supports MCP — path to AgentGuard governance integration
