Feature Request: Provide standalone binary releases for Linux/Ubuntu (for offline/air-gapped environments)

Description

Hi! Thank you for developing such an amazing TUI API client.

I am currently trying to use posting in an air-gapped / offline Ubuntu environment. Because the machine has no internet access, I cannot use uv or pip to install it online, and managing all the dependencies manually in an offline environment is quite challenging.

Proposed Solution

Would it be possible to provide a pre-compiled standalone binary (e.g., packaged via PyInstaller, Shiv, or Briefcase) for Linux/Ubuntu in the GitHub Releases?

Having a single executable file that can be simply downloaded and run (./posting) would be extremely helpful for users in intranet, enterprise, or restricted environments who cannot use uv or standard Python package managers.

Additional Context

• OS: Ubuntu (Linux x86_64)
• Use Case: Offline / Air-gapped development environment

Thank you for your time and consideration!
