feat(engine): expose native technique layers in the consultation output

TASK-consult-evidence-card-v2-20260927 T1. New module
scripts/consultation_native_layers.py, thinly registered after the merged
engine fields in _attach_local_consultation_layers (no handler method, no new
forgery site). It writes one new top-level chart key,
chart.consultation_native_layers, kept out of chart.modules so the thematic
report's full_reading_module_count does not move:

- d9_summary: D9 lagna, each planet's D9 sign and dignity
  (jyotish_engine._get_dignity_level), Vargottama (_calc_vargottama),
  D1<->D9 reversals
- punarphoo (punarphoo.detect_punarphoo, observation_only)
- vivah_saham (jyotish_engine._calc_vivah_saham), day_night (gulika)
- slow_transits: Jupiter / Saturn / Rahu / Ketu now with natal house and the
  Jupiter / Saturn SAV / BAV, and the next twelve months' ingress / station
  dates (ephemeris_events; nodes by the same daily-noon sampling)
- double_transit: cmd_double_transit_pac for houses 1-12, conclusions only,
  plus DK / UL targets by the same PAC rule
- karakamsha, argala, dispositor_chains, inter_chart_linkage, moon_transit
  (lookup-only layers)
- annual_tajika on the annual route: build_annual_tajika_pack (annual lagna,
  Varshesha, Muntha, Mudda Dasha with dates, Sun / Moon / year-lord Tajika
  aspects), parameter_sensitive; blocked when the pack is not reliable,
  never natal data

A/B on 3 public AA charts x 4 routes: every existing output is identical,
only the new key is added; about 40 ms per workflow. Golden regenerated with
annual and timing routes (family workflow byte-identical apart from the new
key).
