Clean enablement of the website Docs section, now that #2253 provides the reorganized + draft-gated content. Flips docs: false → enabled, restores the Documentation navbar item, wraps the sidebar in a generated-index root category, and teaches sync-docs.sh to slug the synced README.md so it doesn't collide with the generated-index root route.

Verified against the current repo + #2253:

• Status/pill parity: welcome.mdx uses exactly Ready / beta in 0.7 / alpha in 0.7, and STATUS_CLASS maps all three — no orphaned status or dead map key (plus a ?? '' fallback for safety).
• CTA route valid: /docs/overview/quickstart resolves — routeBasePath: 'docs' and quickstart exists in #2253, not draft-gated.
• sync-docs README slug handling is well-reasoned: guards against pre-existing frontmatter and keeps the README→index link rewrite so cross-links don't break.

Verdict: APPROVE — correct enablement, verified parity and route, sound sync handling.

Minor (non-blocking, no change needed): the empty exclude: [] block is a leftover scaffold with stray whitespace; the dropped "Try RossoCortex" CTA reads as a deliberate content choice now that docs are live.

Depends on #2253 (the content source — approved and green); merge it first so the synced docs/ exists at build time.

Areas reviewed: Docusaurus config/sidebar, sync-docs shell, React component (status-map parity), content. Commits: 2, signed-off. CI: passing.
