.SYNOPSIS
    Installs (or updates) the TinqsBlenderBridge auto-start module.

.DESCRIPTION
    Copies tools/blender_bridge/tinqs_blender_bridge.py (the server's source
    of truth in this repo) into Blender's user scripts/startup/ folder.
    Startup modules are imported at every Blender launch and their register()
    is called, so the bridge auto-starts on port 19000 from the next launch
    onward. Idempotent -- safe to re-run after editing the server source.

    This does NOT start the bridge in an already-open Blender. For that, in
    the open window: Scripting workspace > open the repo copy > Run Script.

.EXAMPLE
    powershell -File tools\install_blender_bridge.ps1
