fix(presentation): handle force-push, branch-create, empty pushes

PushEvent payloads carry `created`, `forced`, `distinct_size`, and
`ref` flags that I wasn't consulting — the result on the timeline
was "pushed 0 commits" for what were actually branch creations
(distinct_size 0 because the commits already existed elsewhere)
and force-pushes that didn't change the resulting tree.

  * created=true        → "created branch X in repo" + GitBranchCreate icon
  * forced + size>0     → "force-pushed N commits to repo:branch"
  * forced + size==0    → "force-pushed repo:branch"
  * normal + size>0     → "pushed N commits to repo:branch" (unchanged)
  * normal + size==0    → "pushed to repo:branch" (no awkward "0 commits")

Also: drop the instagram, facebook, and steel-horse-adventures
links from the UI header — those represent personae the user no
longer wants to surface from rob.tn.

Tests: +3 in presentation/github.rs covering the new push
branches — 21 total green.
