Thanks for this PR. I built the PR head locally (Swift 6.4, macOS) and tested edit against a throwaway list.

Works as intended:

• setting and clearing a due date by external ID (date-only and with a time)
• priority changes when combined with another flag
• combined edits; notes and other reminders are not clobbered; invalid input is rejected; repeated edits are fine

Two small defects:

1. --priority or --clear-priority on its own is rejected by validate() with "Must specify new reminder content, new notes, or a new due date". Priority edits only work alongside another flag.
2. --clear-due-date and --clear-priority both use .shortAndLong, so they both claim -c. -c alone clears only the due date.

A small patch that fixes both:

Editing due date and priority is the main thing missing for scripting, so it would be great to see this merged and a release cut. Happy to test further if useful.
