Integrate latest mainline companion updates into desktop feature branch

Local main was already updated to origin/main at 8f0e46e, and this merge brings those buddy/docs/env changes onto feat/dev-desktop. The only conflict was .github/workflows/build-desktop-dev.yml, where both branches added the workflow; the resolved version keeps the mainline body and retains the libfuse2 Linux dependency needed for AppImage-oriented tooling.

Constraint: Merge was already in progress from local main at 8f0e46e
Rejected: Abort and re-run merge from scratch | existing index already isolated the single conflict cleanly
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Keep libfuse2 in the desktop dev build workflow unless Linux packaging is revalidated without it
Tested: git fetch origin main; git diff --check; manual resolution of build-desktop-dev workflow conflict
Not-tested: Root TypeScript typecheck because existing generated desktop/src-tauri/target and extracted-natives assets are included and fail independently of this merge
