docs: OpenBroadcast and OpenGuest, the broadcaster-and-guest framework as OpenProfile.md sections (#168)

* docs: OpenBroadcast and OpenGuest, the broadcaster-and-guest framework as OpenProfile.md sections

Anthony: "broadcasters and guests is the usual framework for live audio
shows, radio, podcasts" and OpenProfile.md should carry it so a platform
(anyfans) can match hosts with guests from two files rather than two
forms. OpenExpert folds into OpenGuest: an expert is a guest with
Expertise and Credentials.

OpenBroadcast is the `## Broadcast` section: Show, Kind, Format, Live,
Cadence, Length, Language, Audience (host's own unit), Feed, Topics,
Seeking, Not, Slots, Remote, Book, and Pays / Charges (unstated by
default, because pay-to-play is the thing a guest is most often not
told). OpenGuest is the `## Guest` section: Available, Expertise,
Credentials, Pitch, Formats, Live, Languages, Availability, Lead time,
Remote, Rate, Pays, Appeared on, Press, Book, Not. Matching scores
Topics/Seeking against Expertise/Topics, Slots against Availability,
Pays/Charges against Rate/Pays; both Not keys are absolute; a platform
never fills a key the person did not write. Both landing pages share
profile-section-page.tsx. OpenProfile.md names the two sections in rule
4 and in Related standards. Registered in the four places.
