Plugin: self-hosted auto-updates from Gitea via PUC (hc-8gb)

Vendors YahnisElsts/plugin-update-checker v5.7 under vendor/ and wires it
to poll updates.json on the repo main branch. WP surfaces new versions
via Dashboard → Updates on its normal twice-daily cadence.

PUC is vendored (not a submodule) so Gitea's archive/main.zip — the
download target — includes it. Folder rename on install is handled by
PUC's built-in upgrader_source_selection filter.
