Introducing halflow, an interactive graphical hal editor

I am aware of one or more similar projects, but they did not seem to fit my use case.

This is entirely vibe coded. I have not studied the code. I chose GPL for the code license, but considering this is an ai production, I was wondering, maybe I should change it to 'public domain' ?

Use at your own risk. This software is not for use anywhere it could cause machine damage or personel injuries.

This project is currently 'pre-release' stage. It can be installed via git from [1].
you will need to install sshpass, and have ssh access over the local trusted network to linuxcnc.
Make sure to click 'Setup' before trying to use 'Connect', 'Disconnect', or 'Load hal modules'.
```
sudo apt install sshpass
```

Goals of this project:

1. Visualization of the current running hal config on any LinuxCNC machine over local trusted network.
2. Editing of parameter values, signal names and values.
3. Automatic detection of loadable hal components on the running LinuxCNC instance.
4. Load/Save configuration projects within the linuxcnc/configs directory.
5. Live parameter and pin value displays while connected to a live hal system.
6. Live editing of the running hal via net, setp, unlinkp, loadrt, and related commands over ssh connection to the machine directly via interaction with the nodes in the canvas. This action will be preceded by a popup strongly encouraging the user to first e-stop the machine. This will avoid having to constantly reload linuxcnc after minor edits.
7. Still dreaming...


Of the above list:

(1.) is working on my pc, except the checkbox option "Use localhost" for running halflow directly on the linuxcnc pc, is currently undefined.
(2.) Is working. Known bug: the editor allows you to copy/paste to create multiple instances of singleton components.
(3.) detects installed components; to properly detect custom components make sure you fully installed with:
```
sudo halcompile --install my-custom-component.comp
sudo halcompile --install-doc my-custom-component.comp
```
TODO: find custom python components also.
(4-7) Coming soon...

Signal wire colors default to color codes representing the signal type, but can be edited. If the rat's nest is a confusing mess of same-colored wires, double-click or right click a wire to edit its color. All wires connected to the same output are synced and will change to your edit.

You can also change the wire (hal signal) name, but the current version of halflow gives you no capability to load your edits back into your linuxcnc hal config.
