Merge v0.8.0rc into feat/cursor-cli

Resolved conflicts:
- sdk-options.ts: kept HEAD (MCP & thinking level features)
- auto-mode-service.ts: kept HEAD (MCP features + fallback code)
- agent-output-modal.tsx: used v0.8.0rc (effectiveViewMode + pr-8 spacing)
- feature-suggestions-dialog.tsx: accepted deletion
- electron.ts: used v0.8.0rc (Ideation types)
- package-lock.json: regenerated

Fixed sdk-options.test.ts to expect 'default' permissionMode for read-only operations.
