STAR-lite for atproto space archives, tentative format pitch (and... is it time to just call it STAR?)

tangled.orgstar-lite/spaces-archive.md at main · microcosm.blue/starSTreaming ARchives: stricter, verifiable, deterministic, highly compressible alternatives to CAR files for atproto repositories.

some notes parallel to @dholms.at: I'm confused why the commitment (integrity?) hash would not go in the header CBOR. I like having magic! and it being extensible. combining the "type" and "version" together in a single byte might work?

commitment/integrity separate: og star-lite legacy that we should definitely drop!

the separated-out commitment from the original STAR-lite was because the rest of the the commit is technically optional, because i thought i’d need to be able to archive sub-trees for hubble in hindsight, those could have just been another $type (and also i didn’t go that route with hubble)
