feat(hermes): link the pull request straight into the Hermes run

A run id in a pull request is a string to copy; a link is a page to open. The
console reopens a finished run at /chat?resume=<id> - the prompt Hermes was
given, the evidence bundle it read, the skill it invoked, and the JSON it
returned, all on one page.

That page is the whole answer to "who decided this". Making the reviewer
reconstruct the URL from a bare id is the difference between evidence someone
looks at and evidence someone takes on trust.

run_url is shared rather than formatted at each call site, so the pull request
and the demo monitor cannot drift into pointing at different pages.
