[NITPICK] §2: GLOSSARY.md exists but is not linked from README or CLAUDE.md

[mvillmow]

Finding

Severity: NITPICK
Section: 2
Evidence: docs/GLOSSARY.md (present), README.md (no link to GLOSSARY)
Principle: POLA

A glossary document exists but is not surfaced in the main entry points (README.md or CLAUDE.md). Undiscoverable documentation is only marginally better than no documentation.
