[links] Our impact: MITH links unavailable

[kyuchia]

Page: https://simssa.ca/activities/impact/

Two external links appear unavailable:

1. Omas@MITH → https://github.com/umd-mith/ema/tree/master/Omas

   • Returns 404 (likely repo restructuring).
   • (No proposed action here; awaiting guidance.)

2. Continuo@MITH → http://mith.us/continuo/

   • Currently renders a blank page (see attached screenshot).
   • Proposed action:
     • Replace with the archived/stable repo: https://github.com/umd-mith/continuo
       (Note: “This repository was archived by the owner on Aug 13, 2025. It is now read-only.”)

Questions

• Do we prefer removing unavailable links, annotating them as unavailable, or pointing to archival sources?
