Astrologer ruling 乙14. One condition source, yogas_doshas.calc_nicha_bhanga_raj_yoga
(conditions A-F, now also structured). New scripts/main_yoga_detectors.py turns it
into yoga_engine-shaped rows (zh + en twins) that YogaEngine.detect appends; the
four neechabhanga_* rules are reference_only (kept, renamed, not evaluated).
Card: traditional_yogas canonical 落陷取消（Neecha Bhanga） with 成立条件; compact
yoga entries keep conditions/reductions. Report: category 落陷取消, mixed group,
not raja; personal-report alias neecha_bhanga -> special.
Changed assertion (test_consultation_yoga_detection_merge): canonical name
'Neecha Bhanga Raja Yoga' -> '落陷取消（Neecha Bhanga）' (ruling 乙14).

TASK-upstream-sync4-20261002 T6, decision 4. Visible parallel calculators were
found in three places and all now read jaimini:
- yogas_doshas.calc_arudha_lagna / calc_upapada_lagna (house number taken as an
Aries-based sign index, no 1/7 exception) are deleted; the module's
arudha_lagna / upapada_lagna fields come from jaimini.
- special_lagnas.calculate_arudha_lagna / calculate_upapada_lagna ("count from
the landing" 1/7 exception, which disagrees with jaimini when the lord is
4th/10th from the source) are deleted; the full reading's Arudha_Lagna /
Upapada_Lagna rows are built from jaimini padas.
- the transit multi-reference table took "ascendant degree + 12th-lord degree"
as AL; it now uses jaimini's A1.
jaimini's own exception counting is unchanged (astrologer question 5); the
upstream "count from the landing" variant is not ported. A10 in special_lagnas
keeps its own exception rule (outside decision 4; listed in progress).
