docs: pointers as descriptive links per STYLE.md; hypertext-links skill

Pointers section now uses [descriptive text](url) links with
frontloaded, context-free anchor text (intra-repo relative paths for
local docs; mm-diigo repo link for the provenance collection).

New opencode skill hypertext-links encodes the Prism
docs/research/STYLE.md link rules for reuse here.
