Compound Engineering plugin view now renders the dashboard's shared ViewHeader (Sparkles icon + title) so it matches the other main-content views. Expose ViewHeader via the dashboard exports map; resolve it in the plugin via an ambient interop declaration (no host runtime dependency). Tests updated (plugin suite green).

A new workspace-acyclicity invariant on main (run via the PR merge) flagged
compound-engineering -> @fusion/dashboard -> compound-engineering: the plugin is
listed in @fusion/dashboard's deps (for view loading) AND declared @fusion/dashboard
as a runtime dependency, which the cycle check (deps+devDeps) and the
'bundled plugins must not depend on host packages' check both reject.
The plugin's only @fusion/dashboard use is the type-only PluginDashboardViewContext
import. Drop the @fusion/dashboard dependency and resolve that type via an ambient
dashboard-interop.d.ts + tsconfig paths mapping (the fusion-plugin-dependency-graph
interop pattern). Breaks the cycle; the host passes the real context at runtime.
