Stable per-branch report URLs and a reachable live view (v0.9.8)

A report directory holding a single page is now linked and served as a
directory, so Gradle's --profile report has a stable permanent URL although
its file name carries the build timestamp.

The permanent link moves to the build it resolves to — the branch's latest
green build — and appears on every build table instead of only the branches
view. The Current tab gave way to a link in the artifacts column, shown
while a build runs; /current itself stays routable.
