plan(workplans): add ATLAS-WP-0003 (connectors) and ATLAS-WP-0004 (explain & graph)
Phase 2 (ATLAS-WP-0003): read-only discovery connectors reusing repo-scoping's
scanner/candidate/approval pipeline — connector contract, repo-scoping fact
ingestion, git-config scanner, feature-control flag connector, stale/unowned
detection.
Phase 3 (ATLAS-WP-0004): effective-config explain + knowledge graph — static
override-path resolver, config explain tool, config-typed edges to the State Hub
graph, blast-radius view, determinism tests.
File-first per ADR-001; state_hub ids to be written by fix-consistency.
