"#54" made Frank go hunting: numbers are per-repository across the forges this
fleet uses, and a number carries no hint of which work is being reported. Every
mention of a PR now pairs its web URL with its title — gitea.franksdank.cloud for
the Dankclaw Gitea, the equivalent for any other forge.
Refs the AGENTS.md convention that an open PR gets opened in Frank's browser: the
rule covers prose, where the browser tab does not help.
