feat: Add amd64v3 build artifacts

[kimpepper]

This PR adds support for building amd64v3 optimized binaries alongside the existing amd64v1 binaries for the Skpr CLI. It also introduces a new snapshot-release task for local testing of releases.

Changes:

• Configured GoReleaser to build both amd64v1 and amd64v3 variants for Linux and macOS platforms
• Updated archive naming template to differentiate between amd64 microarchitecture levels
• Added a new snapshot-release task to .mise.toml for local testing

skpr_1.3.0-SNAPSHOT-e1cdaa8_checksums.txt
skpr_1.3.0-SNAPSHOT-e1cdaa8_linux_amd64.deb

As per convention, deb and rpm filenames follow the pattern linux_amd64 (no version for v1) and linux_amd64v3 for v3 packages.

Also adds a mise snapshot-release task.
