refactor(phase0): source-agnostic formatter/gating scaffold + harness (inert) (#28)
Foundation for making all hazard formatting+gating source-agnostic. ZERO
behavior change — the formatter/decider registries are empty (get_formatter/
get_decider return None → existing precomposed/Mode-B path preserved), and the
shadow comparator is off unless MESHAI_SHADOW_CATEGORIES is set.

- notifications/formatters/ (registry+dispatch with family fallback), gating/
  (GateResult + deferred-commit contract), both empty registries.
- notifications/clock.py determinism seam; route wfigs/quake/nws gating time
  reads through it (identical values) so goldens can freeze time.
- formatters/_budget.py = copy of central/budget.py; central/budget.py is now a
  re-export shim (import-smoke test guards it).
- compose_mesh_message consults the registry first (verbatim, no Mode-B re-cap),
  falls back to legacy; _resolve_budget injects per-category budget.
- notifications/shadow.py + two DRY-RUN hooks (consumer._normalize, dispatcher
  render): compute the new result and diff-log SHADOW_MISMATCH JSONL, but NEVER
  commit/emit/write tables and always broadcast the OLD result. Inert by default.
- tests/harness (pinned_time/pinned_tz, byte-golden, gate-sequence) +
  scripts/capture_fixtures.py (ephemeral read-only NATS capture); tzdata pinned.

Tests: +60 (18 scaffold + 42 harness/shadow); 0 new failures (34 baseline).
