docs: promote distribution to its own section

[jal-co]

What

Promotes GitHub registries out of the CLI nav group into a new top-level Distribution section, and adds a companion Hosted Registry page so the section has two peer pages.

- index
--- Distribution ---   hosted, github-registries
--- CLI ---            options, init, eject, prompts
--- Output ---         project-structure, frameworks, docs-engines

• New www/content/docs/distribution/ with hosted.mdx, github-registries.mdx (moved from cli/), and meta.json.
• Root + CLI nav meta updated.
• All inbound links repointed to /docs/distribution/github-registries (index, options, prompts, README).

Why

GitHub source registries and the hosted build-and-host model are distribution choices — how your registry is shipped — not CLI command reference like options/eject/prompts. A dedicated section signals that and pairs the two models side by side. Follow-up to #38.
