Force the builder stage to run on the host BUILDPLATFORM and cross-compile to TARGETARCH natively, avoiding QEMU emulation on arm64. Also wire version metadata through ldflags and bump the publish workflow to emit both linux/amd64 and linux/arm64. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Summary
Our published container images are currently amd64-only, which means anyone running on Apple Silicon (M1/M2/M3/M4) or arm64 Linux has to fall back to slow emulation or cannot run the image at all. This PR turns on multi-arch publishing so we ship both linux/amd64 and linux/arm64 from the same release.
The build is configured to compile natively for each target architecture from a single host, rather than emulating arm64 under QEMU. In local testing a full two-architecture build completed in about 1 minute, compared to 15+ minutes when relying on emulation. This unblocks Apple Silicon developers and cuts CI time significantly.
As a small bonus, version, git commit, tree state, and build date are now baked into the binary and logged at startup, which makes it easier to tell which build is running in a given environment.
