docs: five-tab menu and a clean landing page

[imran-siddique]

ca2a.agentrust-io.com opened with eight top-level menu entries: Home, Quick Start, How It Works, Configuration, Tutorials, Specification, Testing and Project. Testing held one page, three entries were single pages beside sections, and the home page carried a left menu and a table of contents beside its landing cards. The AgenTrust docs sites are moving to one menu shape, and this applies it here.

Menu, before and after

• Before: Home, Quick Start, How It Works, Configuration, Tutorials, Specification, Testing, Project.
• After: Home, Get started, Specification, Guides, Project.
• Get started holds Quick start, How it works and Configuration.
• Specification keeps Overview first, then groups its 16 pages four apiece: Profile and transport, Delegation and policy, Attestation, and Conformance and failure.
• Guides holds the five tutorials and Hardware validation, which was the only page under Testing.
• Project holds Limitations, Roadmap, Governance, Technical charter, Sponsors, Contributing, Changelog, Security, Code of conduct and Privacy.
• Labels move to sentence case. No file is renamed, so every URL is unchanged.

Theme and landing page

• header.autohide is removed, leaving the feature set the other docs sites use: navigation.instant, tracking, tabs, tabs.sticky, sections, top, path, search.suggest, search.highlight, content.code.copy, content.tabs.link and toc.follow.
• index.md front matter adds hide: [navigation, toc], so the home page renders full width with the tabs only. Inner pages keep both sidebars.

Checked

• The 37 nav entries before and after are the same set; the diff is empty.
• Replicated the Docs workflow: copied docs/ and the root allowlist into .docs_build, rewrote docs_dir, and built with the pinned requirements/docs.txt (mkdocs 1.6.1, mkdocs-material 9.7.7). The build exits 0, and --strict also exits 0 with no warnings.
• In the built site the tabs read Home, Get started, Specification, Guides, Project on the home page and on /docs/concepts/. The home page's primary and secondary sidebars carry hidden; /docs/concepts/ shows both.
• Headless Chrome screenshots of the home page and /docs/concepts/ at 1400x900 show the five tabs and the full-width landing.
