introducing diffmap: a new document format for planning and reviewing agent code.

The idea behind diffmap is letting you review the important design changes, not massive line diffs.

"Write a diffmap spec for the changes on this branch. Use http://github.com/tanishqkancharla/diffmap"

I've been working and iterating on this skill for more than 2 months! I use it every day for any big feature or refactor. Excited to finally make it public
