Profekcje roczne (LOG-10) i Solar/Lunar Return (LOG-12)

Pierwsze techniki predykcyjne.

Profekcje (LOG-10):
- engine/profections.py: Whole Sign, wiek mod 12; profektowany Asc + Władca Roku
  (władca domicylowy) + profekcje MC/Su/Mo. Obsługa 29 lutego.
- endpoint /chart/profections (zakres lat: start_age, count).

Returns (LOG-12):
- engine/returns.py: moment powrotu Słońca/Księżyca do długości natalnej;
  skan dobowy + bisekcja do ~sekundy, z pominięciem artefaktu zawinięcia 0/360.
- endpoint /chart/return (kind solar|lunar, around) — zwraca pełny horoskop
  na znaleziony moment (oba warianty użycia po stronie technik wyżej).

Walidacja:
- profekcje zgodne co do joty z tabelą astro-seek z notes3 (wiek 0..42:
  Asc + Władca Roku + MC/Su/Mo).
- Solar Return 2026: Słońce wraca do Tau 10°08'22" = natalny stopień;
  Lunar Return trafia natalny Księżyc <2'; samospójność potwierdzona.
- 62 testy przechodzą (nowe: test_profections, test_returns).
