The docs stop calling built things "not yet": custom domains, landing on green, a proposal's nod and feed paging #7209

For: a reader of the docs, person or agent, learns what the forge does today, not what it did months ago.

These lines say a feature is missing when it is built:

• docs/STATUS.md:135 and docs/ARCHITECTURE.md:716 say "Not yet: … custom domains, and a gate that lands a pull on its own". Custom domains exist (MCP app_domains, src/http/mcp/tools/app_domains.ts), and landing exists (src/checks/landing.ts, the merge queue in src/checks/queue.ts).
• docs/PLANNING.md:631 says "A person's nod that opens a stored proposal is not built yet." It is built: src/actions/proposals.ts with approve, plus the inbox card and MCP asks_proposal.
• docs/FEED.md:83 says paging past the first 20 is not built. src/web/studio/feed.ts:306 takes ?cursor= and links to older posts.

Done:

• [ ] Each line above says what is built, in one sentence, and names its module. Anything really still missing stays listed. Check "containers around apps" against the cells, "stop from a card" against the feed, federation and a package registry before you keep or drop them.
• [ ] No other file under docs/ says one of these four things is missing (grep -rn "not yet\|not built" docs).
• [ ] bun test passes. Docs tests such as test/cluster-doc.test.ts may pin some of this text.

Files: docs/STATUS.md, docs/ARCHITECTURE.md, docs/PLANNING.md, docs/FEED.md. Risk: none. Docs only.
