distribute/base.py: Artifact dataclass + Distributor protocol + idempotent
BEGIN/END snippet markers (upsert_block replaces a pattern's block in place so
re-distribution doesn't duplicate) + agnostic markdown body rendering from
SolutionPattern fields. BaseDistributor honours per-flavor body/target hints.
8 new tests; suite 110/110.

Three workplans queued and registered with the State Hub (via REST — MCP write
layer is erroring this session):
- AGENTIC-WP-0007 Phase 3 Distribute: per-flavor distributor adapters render
approved catalog patterns into proposed (HITL) artifacts, scoped by repo/domain.
- AGENTIC-WP-0008 Read-before-Edit reflex: act on the #1 friction finding.
- AGENTIC-WP-0009 Phase 4 Measure: baseline + before/after effectiveness + trend.
Proceeding in that order.
