Add ARM Support

[jeff-hykin]

test on an Arm system with:

uv pip install "dimos[unitree] @ git+https://github.com/dimensionalOS/dimos.git@jeff/arm_support"
dimos --replay run unitree-go2

Just uses the stop-gap pypi package published at: https://github.com/jeff-hykin/open3d_jetson
Which is just pre-build wheel files for arm based on the open3d repo

Greptile Overview

Greptile Summary

This PR adds ARM (aarch64) Linux support by introducing the open3d-unofficial-arm package alongside the existing open3d dependency. It also includes a temporary workaround in spec.py to fix CI by hardcoding the list of LangChain providers instead of importing them dynamically.

uv.lock
bitsandbytes markers removed

This lock change removes the sys_platform != 'darwin' and sys_platform != 'win32' markers for bitsandbytes deps, so the lock now claims packaging/torch (and the numpy pins) unconditionally. Since the only wheel listed here is manylinux...aarch64, resolution/install on macOS/Windows is likely to break or at least become inconsistent with the previous intent. If this PR’s goal is ARM support, the platform markers should remain so non-Linux platforms don’t try to resolve/install bitsandbytes from this entry.

this change was on dev at some point idk how it got removed but it causes problems because xcbuild is a macos tool

[jeff-hykin]

This is the ONLY change that should be in this PR, everything else is to pass CI
