Repo was renamed podkop-evolution -> netshift. Update every code/docs
reference to the new repo so update checks, package downloads and the
default-config fetch hit netshift directly (podkop-evolution stays only
as a one-time compatibility bridge):
- install.sh: REPO + rate-limit check + raw config URL + banners
- bin/netshift: update-check API + issue URL
- README badges/star-history/config URL; ISSUE_TEMPLATE links
- realign install.sh banner frames after the shorter URL
- add docs/icon.png
