Multiple small issues with breadcrumbs
Root workflow
On a normal root workflow (eg https://debusine.debian.net/debian/developers/work-request/234351/) you get this:
It should really have "SCOPE / WORKSPACE / workflows / TITLE" and the "workflows" text should link to /SCOPE/WORKSPACE/workflow/. I understand we have the workflow link and switcher in the header bar, but conceptually I find it strange to skip that level the page hierarchy in the breadcrumb.
Collection
Similarly on a collection (https://debusine.debian.net/debian/developers/collection/debian:qa-results/sid/) you get this:
It should have "SCOPE / WORKSPACE / collections / NAME@CATEGORY". The collections word should link to the list of collections and the breadcrumb entry should have the full page title, i.e. name and category.
BTW, in general I think the H1 title should go away in favor of the breadcrumb text.
Collection item view
In a collection item view (https://debusine.debian.net/debian/developers/collection/debian:qa-results/sid/item/2333420/autopkgtest_cinder_2:27.0.0-1_amd64_214879/) you don't get the hierarchy at all. In the above case, you have the name of the item or associated artifact:
Collection browse page
In a collection browse view (https://debusine.debian.net/debian/developers/collection/debian:qa-results/sid/search/), you get the name of the collection twice. I think the second name should be "browse" or "search" depending on which name you prefer (URL is search, button/title is Browse").
Create artifact and create work request pages
The create artifact and create work request pages in the plumbing area also lack the hierarchy but that's not a big issue given the low importance of those pages. Maybe we should even consider dropping them because they are not up-to-par compared the corresponding CLI interface.
Group view
In the group membership view (https://debusine.debian.net/debian/-/groups/Debian/) you get this:
It doesn't make any sense that the parent page is the user profile page. We don't have a list of groups page, but I'd prefer a "groups" word without a link rather than this.
