ci: move image build off-infra to GHA -> ghcr (ADR-0002)

Generated by infra/scripts/offinfra-onboard: GHA builds+tests on the
GitHub mirror, pushes ghcr.io/viktorbarzin/freedify, then triggers the
Woodpecker deploy (repo 202). Old in-cluster build pipeline
removed: .woodpecker.yml

+# Off-infra build (ADR-0002). Canonical repo is Forgejo viktor/freedify, which
+# push-mirrors here; this workflow builds on GitHub-hosted runners, pushes the
+# image to GHCR, then signals the Woodpecker deploy pipeline (repo 202)
+# to roll the cluster — the homelab never sees build IO or registry pushes.
+#
+# Committed on the FORGEJO side (the mirror is one-way; commits made on GitHub
+# are overwritten by the next sync). Generated by infra/scripts/offinfra-onboard.

-            The AppImage requires `webkit2gtk-4.1` to be installed on your system:
-
-            **Ubuntu/Debian:**
-            ```bash
-            sudo apt install libwebkit2gtk-4.1-0
-            ```
-
-            **Arch Linux:**
-            ```bash
-            sudo pacman -S webkit2gtk-4.1
-            ```
-
-            **Fedora:**
-            ```bash
-            sudo dnf install webkit2gtk4.1
-            ```
-
-            After installing the dependency, make the AppImage executable:
-            ```bash
