This is PR 2 of 3 in a stacked PR sequence for MCP Apps in Goose2.
The full feature delivery depends on all three PRs merging. This PR stacks on PR 1, and PR 3 stacks on top of this one.
With the ACP surface in place, this PR is the big host/bootstrap pass for Goose2 itself. It adds the sandbox proxy, the Tauri command plumbing, and the initial inline app host so Goose2 can actually load an MCP App resource, bootstrap the app view, send host context and tool updates, and proxy app requests back through ACP.
This is the PR where Goose2 starts acting like an app host rather than just a chat UI. The follow-up PR tightens the render decision and makes it
tools/list-driven, but this one is what gets the bridge and runtime in place in the first place.If you're reviewing this slice and want to see how it's supposed to work, start with the sequence diagram and notes in #8594.
Related to #8594.
