[codex] Add Linux ARM64 CLI binary build

[Antoninj]

What changed

Adds a Linux ARM64 target to the CLI binary build matrix so releases publish a portabase_linux_arm64 artifact.

Why

The installer maps aarch64 hosts to arm64 and expects portabase_linux_arm64 plus a matching checksum entry. Current releases only publish portabase_linux_amd64, so the installer fails on Linux ARM64 with Checksum not found for portabase_linux_arm64.

Validation

• git diff --check
• Checked the workflow file contains the new Linux ARM64 matrix entry

Summary by CodeRabbit

• New Features
  • Added an additional Linux arm64 build target, expanding available binary artifacts for compatible systems.

Poem

🐰 I hopped through YAML with a twitchy nose,
Found an arm64 path where the build wind blows.
One tiny matrix row now joins the bay,
Binkies for binaries, hooray hooray!
