Suggest `skynet.dgpu` docs, typing, pythonisms 

From the deep-ish dive drafting our first set of design/architecture
diagrams in https://github.com/skygpu/cyberdyne/pull/2, this adds
a buncha suggestions, typing, and styling adjustments.

Namely the code tweaks include,
- changing to multi-line import tuples where appropriate (since they're
  much handier to modify ;)
- adding typing in many spots where it wasn't clear to me the types
  being returned/operated-with in various (internal) methods.
- doc strings (in mostly random spots Xp ) where i had the need to
  remember the impl's purpose but didn't want to re-read the code in
  detail again.
- ALOT of TODOs surrounding various potential style changes,
  re-factorings, naming and in some cases "modernization" according to
  the latest python3.12 feats/spec/stdlib.
