Verify docs.libresign.coop refresh after release docs deploy

[vitormattos]

Context

PR #103 updated the LibreSign release documentation to the current ownership model.

Validated

• main/developer_manual/release-process.rst describes LibreCodeCoop/release-tool and LibreCodeCoop/.github correctly.
• manual.rst and configuration.rst are also corrected.
• Deploy Sphinx Docs run 35950662046 completed successfully for merge commit a8e42b8e72a21cd3cb8d387ce6872a649800c043.
• gh-pages commit 58eed721bf70e276eab677984656714cb91ca92e contains the corrected generated HTML.
• gh-pages/CNAME is docs.libresign.coop.
• current repository/code searches contain no LibreCodeCoop/github-workflows references in the documentation source.

Remaining verification

External web search still returns a crawl from several days before #103, so search results can display the previous release-process content. That stale crawl is not evidence that the current GitHub Pages origin is stale.

The current execution environment cannot perform an uncached live-origin HTTP/DNS check of docs.libresign.coop. Verify the custom domain in a browser (or with an uncached HTTP request) and close this issue once the rendered release-process page matches the current gh-pages content.

This is a publication/search-refresh verification item, not an active dependency on LibreCodeCoop/github-workflows.

[vitormattos]

Clarification after deeper verification: GitHub-side publication artifacts are current. The gh-pages branch generated by run 35950662046 contains the corrected release-process, manual, and configuration HTML with no LibreCodeCoop/github-workflows ownership references. The stale public text observed through web search/open came from a crawler snapshot several days old, not a confirmed live-origin fetch. A direct network fetch is unavailable from this execution environment.

Therefore this issue should be treated as a verification item for the custom domain/search cache, not evidence that the current gh-pages deployment itself is wrong. The repository source and generated Pages branch are clean.
