Adds the foundation of the feature-module architecture
(docs/frontend-modularization.md) as inert, additive code:
- kernel/feature-registry.js: window.LP.features — runtime register(),
manifest loader, route-table + nav builders.
- features/manifest.dev.json: hand-committed manifest mirroring spa.js
setupRoutes() exactly (route -> handler + navId).
- index.html loads the kernel before spa.js.
Zero behaviour change: nothing consults the registry yet. Phase 0b flips
routing to be registry-driven with the spa.js Map as fallback.
