docs(clade): uuid follows the forge path, it is not immortal (#91)

Comment-only correction in `.machine_readable/CLADE.a2ml`. The status
comment said the uuid is immortal. gv-clade-index ADR 0007 (accepted
2026-11-10) makes the uuid follow the forge path: a move or rename mints
a new one, and a phase change never does. The comment's "A rename is NOT
a phase change" now says "A prefixed-name (clade code) change", the
rename it means. Paragraph re-wrapped at 80 columns; no data value
changes.
