refactor: remove embedded AXS debug path

Remove the debug-only asset refresh flow from the terminal plugin and terminal session startup.

Keep AXS acquisition on the normal download path so debug and release share the same runtime behavior.

This also drops the PTY retry path that depended on replacing the local binary from bundled assets.
