chore(lint): remove banner separators and narrating comments

Converts decorated section banners to plain comments or drops them, and
sweeps the noisiest files for comments that restate the code or name
what follows. Field-level notes that carry units, enums or invariants
move to TSDoc. Comment-only: the non-comment token stream of every
changed file is identical.
