* ci(docker): publish multi-arch images (linux/amd64 + linux/arm64)
The Dockerfile was already arch-aware (TARGETARCH in the Jellyfin apt
repo); this adds linux/arm64 to the buildx platform list so the pushed
manifest list serves both x86 servers and arm64 hosts (Apple Silicon,
Graviton, Pi 4/5). Verified locally on the arm64 runner host: image
builds and both silo and jellyfin-ffmpeg run.

* ci(docker): move image builds to GitHub-hosted runners
Replaces the single self-hosted job with a per-arch matrix (ubuntu-latest
for amd64, ubuntu-24.04-arm for arm64) so each platform builds natively
with no emulation, pushing by digest, plus a merge job that stitches the
digests into one tagged manifest list. Layer caching moves from the
persistent local builder to type=gha per-platform scopes.
The private-SDK constraint that originally forced self-hosted no longer
applies: silo-plugin-sdk is public and resolves from proxy.golang.org.

* ci(docker): use normalized IMAGE_LC in merge-job metadata step
Not a functional fix — metadata-action lowercases the images input
itself (proven by run 29768620803) — but keeps all image references in
the merge job on the explicit IMAGE_LC form.

The issue form only applies labels for web-form submissions; contributors
filing via API/CLI or from a fork lack the triage/write needed to set
labels, so their proposals landed unlabeled and never auto-added to the
Silo v1 project. Add an issues:opened workflow that stamps v1-proposed on
any [v1]-titled issue via the repo GITHUB_TOKEN, regardless of filer
permission.
Also drop epic from the proposal template's auto-labels: a fresh proposal
is a candidate, not yet a tracked epic. epic-ness (better: the Epic issue
type) is applied at acceptance/lock alongside v1 + milestone.
