v6.0.19: fix degraded mode - Muntha no longer skipped without swisseph

Bug: v6.0.18's solar_return_full_report returned early when calc_solar_return_chart
failed (no swisseph), skipping Muntha entirely.

Fix:
- Added _estimate_sun_sign() with lookup table for sun sign from birth date
- Refactored solar_return_full_report to use degraded mode:
  - Muntha + Year Lord always computed (using lookup table sun sign)
  - Tajika/Sahams/Tri-Pataka/Mudda gracefully skipped with notes
- Added _SUN_SIGN_LOOKUP table covering 1950-2100, \u00b11 sign accuracy

v6.0.18: Solar Return/Varshaphala 实现 + Muntha covered

变更概要：
- scripts/solar_return.py（新）：太阳返照盘核心计算（二分法求精确UT时刻）
- scripts/cmd_solar_return.py（新）：solar-return 子命令
- scripts/jyotish_engine.py：新增 Step 4.12 + cmd_solar_return 注册 + --target-year 参数
- references/technique_registry.json：muntha→covered，新增 solar_return（covered）
- CHANGELOG.md：新增 v6.0.18 条目
- SKILL.md：版本 6.0.18

已知限制（待修复）：
- swisseph 不可用时，calc_solar_return_chart 报错导致 solar_return_full_report 提前返回，Muntha 计算被跳过。
- 修复方向：将 calc_solar_return_chart 拆为 UT 计算（近似算法可用）和 chart 计算两步，chart 失败时不中断 Muntha 计算。
