Add PID 1209:A69A for Uncommon Group Lagrange

[uncommonRaum]

Requesting PID 1209:A69A for the Lagrange USB-UART Bridge.

Project: https://github.com/UNCOMMONGROUP/Lagrange

An open-source USB CDC-ACM to UART bridge built on the Renesas RA2L2
(Arm Cortex-M23) MCU, supporting baud rates up to 1.5 Mbps. Rather than a
fixed-function bridge IC, the conversion runs entirely in firmware, so the
same hardware can be retargeted to other interfaces in future releases.

Licensing:

• Firmware: MIT — LICENSE
• Hardware: CERN-OHL-S v2 — LICENSE-hardware

The repository contains the complete e2 studio firmware project, schematic,
PCB design files, production data (Gerber/BOM/PnP), and the enclosure model.

I checked the PID list and A69A is unassigned. Happy to pick a different
one if it conflicts with a pending request.

This project includes open source hardware (altium) and software in the linked project and appears to me to be eligible for a pidcode.

I recommend merging once the CI is done.

[cnlohr]

@uncommonRaum your commit is in the incorrect format. Please commit your PID in the format as all the other PIDs.

I.e.

1209/a69a/index.md

[uncommonRaum]

Thanks! Fixed — moved to 1209/A69A/index.md to match the standard format.

[uncommonRaum]

@cnlohr The CI run expired waiting for approval (30 days), so it shows as
failed. The path has been fixed to 1209/A69A/index.md as requested.
Could you re-approve the workflow so it can run?

[cnlohr]

PDFs and source hardware files included, everything appears fine.

[cnlohr]

Ugh I have no idea why the tools won't make forward progress. Can you kick it one more time and @ me in thread once you do?

[cnlohr]

Ok, I think this PR is broken, can you re-open a new one, @uncommonRaum ? Please reference this PR when opening it so I can quickly approve, and also @ me in the new one so I will see it.

[uncommonRaum]

Closing in favor of a fresh PR as requested. Thanks @cnlohr!
