Description

Adds a Linux arm64 binary (quill-linux-arm64) to the release assets. macOS arm64 was already built; Linux arm64 was the missing piece.

• New linux-arm64 entry in the release.yml matrix, built natively on GitHub's ubuntu-22.04-arm runner (free for public repos). Building natively avoids cross and keeps all default features, including Ledger (the arm32 build has to drop it for armv6 compatibility).
• Uses Ubuntu 22.04 to match the glibc baseline of the existing x86_64 Linux build.
• README: lists the new asset and fixes the arm32 asset name (quill-arm_32 → quill-linux-arm32, which is what the release actually uploads).
• CHANGELOG entry under Unreleased.

Windows arm64 (windows-11-arm) is not included; it would need the HID/vcpkg setup checked first.

How Has This Been Tested?

• actionlint passes on the workflow.
• The release workflow also runs on pull_request, so the Release binary for linux-arm64 job on this PR exercises the build (upload only happens on tags).

Checklist

• I have made corresponding changes to the documentation in docs/cli-reference. (N/A — README updated instead)
• I have added corresponding integration tests. (N/A — CI-only change)
