feat: add ARM64 deploy variations for linux and windows

[RachHavoc]

Description

Adds ARM64 deployment variations for linux and windows platforms, mirroring
the darwin ARM64 support added in #435.

Type of change

• New feature (non-breaking change which adds functionality)

• data/abilities/command-and-control/2f34977d-9558-4c12-abad-349716777c6b.yml

  • Added architecture: AMD64 label to existing linux and windows variations for consistency with darwin
  • Added full ARM64 variation set for linux (curl + -H "architecture:arm64")
  • Added full ARM64 variation set for windows (PowerShell WebClient + .Headers.add("architecture","arm64"))

How Has This Been Tested?

Copy + Pasted Sandcat Agent code from UI on the following ARM based VMs. Successfully got beacons and was able to send instructions to the agent.

Tested on:

• Linux ARM64 (e.g. Graviton / Raspberry Pi)
• Windows ARM64

Checklist:

• My code follows the style guidelines of this project
• I have performed a self-review of my own code

Notes

Windows ARM64 sandcat binary may need to be cross-compiled separately if not
already present in payloads/. See build instructions in README.
