README wishlist review gentle nudge (H-net, MEGAKERNELS, State-space hybrid)

[greqone]

Hey folks, gentle poke poke on a few of my non-record submissions when someone has review bandwidth. No rush, I know the queue is huge, but these are the ones I think are actually worth a look:

• #1044 H-Net byte tokenization
• #1138 whole-model megakernel path
• #1404 state-space hybrid with attention anchors
• #394 PR315 Backout + FA3 RunPod non-record
• #252 PR114 RunPod H100 SXM non-record

Mostly hoping for a sanity/review pass rather than leaderboard urgency. If any are too rough or better framed as research notes, happy to adjust.
