rename CONTEXT.md/CONTEXT-MAP.md convention to GLOSSARY.md/GLOSSARY-MAP.md

The prior commit renamed only this repo's own root glossary. This
commit does the thing actually asked for: repoint every skill and doc
that reads/writes the domain-doc convention in consumer repos —
domain-modeling, grill-with-docs, improve-codebase-architecture,
setup-matt-pocock-skills, triage, tdd, diagnosing-bugs, ask-matt,
codebase-design, wait-what — plus their docs pages, .agents/ notes,
and the top-level README. CONTEXT-FORMAT.md is renamed to
GLOSSARY-FORMAT.md alongside it.

Left untouched on purpose: CHANGELOG.md and the one still-unreleased
CONTEXT.md-era changeset, both historical records of what shipped
under the old name; and the README's pinned course-video-manager
link, which points at a real file that is still literally named
CONTEXT.md at that commit in another repo.
