v12: Handmerge main into v12 - 2026-Mar-23

[mathomp4]

Supersedes #182

This is a handmerge of main into feature/sdrabenh/gcm_v12. This mainly gets in some PRs that have recently been in main:

• Verify MERRA2 location; ensure correct WEMIN setting for remapping from MERRA-2 and GEOS-IT #188
• Handle SLURM constraint; add blend script #187
• v11: Update remap test cases baseline #186

Now, the main reason I didn't just push this was because of #188 which fixed the WEMIN bits.

I think this is fine but I want @biljanaorescanin, @weiyuan-jiang and @gmao-rreichle to say "Yes, even v12 needs this" before I merge in.

@mathomp4 : Based on a very quick inspection, the source code changes look ok to me. It would be good for @biljanaorescanin and @weiyuan-jiang to double-check.
I don't know how much effort we want to put into CHANGELOG.md. I think we missed a CHANGELOG.md entry for #188 in the original PR, and it's consequently missing here. If you're ok with it, so am I.

Yes, we need this fix. But this "bug" will not show up in this remap_package if the users go through the normal process
