docs: add ADR-106 matter data model [ADR-1179]

Why this matters

When provenance and live data share one column, the matter's birth certificate is lost.

STORY nine-eighty-eight

Mixed storage = no provenance, no queries, no enforcement.

The fix — Snapshot the birth, live the work, never mix the two.
