docs: name OHM as the corpus, "Human" as the first RFC

Reframe the Open Human Model in SPEC.md and PHILOSOPHY.md from "the
first RFC the framework will produce" to "the corpus of RFCs the
framework produces, of which the first defines *human*." Earlier
phrasing collapsed the project (OHM) and the first entry into one
name; this teases them apart.

Also surface the OpenXML APIs / UX downstream-consumer point: OHM is
English-first by design — the markdown bodies are canonical, and the
structured artifacts downstream systems need to actually let humans
and machines interact are derived from that English source, not
authored alongside it. This is part of why markdown round-trip
fidelity matters structurally (cf. the Phase 1 CM6 swap).

Updates the obvious example renames — slug `open-human-model` →
`human`, title "Open Human Model" → "Human", PR-list / breadcrumb /
notification examples — so the SPEC's worked-example consistently
shows OHM-as-corpus with Human as a member. Test fixtures and the
README seed-script invocation still carry the old slug; those are
left for a separate pass.
