v1.1 — Transparent auspicious picking 择日增强

pick_auspicious_dates now supports patron_birth (福主生日):

Patron zodiac match — days clashing (六冲) or harming (六害) the patron's zodiac are vetoed; 三合/六合 days get +15 with bilingual reasons.
Fixed inauspicious days hard-veto — 杨公忌 / 三娘煞 (weddings) / 十恶大败 / 四离四绝 (computed from minute-precision solar terms).
Transparent split — engine_score (0-5 four-tier arbitration) and local_adjustment are reported separately, never double-counted.
pick_dates_deep — day-by-day scan for burial 安葬 & ancestor worship 祭祀 (no engine shortlist exists for these), capped at 31-day windows.
All scoring logic is ported from and cross-validated against the tung-shing-almanac-skill Python engine — 249 test vectors, 100% match.
🌾 24 solar terms 二十四节气 — minute precision (JPL DE440s ephemeris, 1900–2100)
🛡️ Watermarked, rate-limited API — data provenance & DMCA-ready (server-side engine stays closed-source)
