CLAUDE.md, a README, and the roadmap to full ActivityPub interop

CLAUDE.md records what the project is (one private login owning unlinkable
personas, each its own actor), the deliberately odd route names (peasants,
mouth, anus, human-centipede, sniff/again, and the agreed ones still to come),
the federation and privacy invariants, the data and style conventions, and
how it deploys. docs/ROADMAP.md holds the intent reconstructed from the 2023
code, the gap audit, the owner's decisions of 2026-10-01 (Mastodon client
API, personas unlinkable to others, local-only range posts, communities and
circles), the libraries chosen, and phases P0-P5.
