Resolve type inconsistencies in `is_condition_met()` across `Yaku` subclasses

[Apricot-S]

Summary

Some Yaku subclasses override is_condition_met() with signatures that are not type‑compatible with the base class.
This causes mypy errors and violates Liskov substitution principles.

Unifying these method signatures may require API changes and could become a breaking change.

Example

class Yaku:
    def is_condition_met(self, hand: Collection[Sequence[int]], *args) -> bool: ...

class SanKantsu(Yaku):
    def is_condition_met(self, hand: Collection[Sequence[int]], melds: Collection[Meld], *args) -> bool: ...

class KokushiMusou(Yaku):
    def is_condition_met(self, hand: Optional[Collection[Sequence[int]]], tiles_34: Sequence[int], *args) -> bool: ...

Scope

• Identify all Yaku subclasses whose is_condition_met() signatures differ from the base class
• Refactor the method signatures to be type‑compatible
  e.g., unify parameters, use *args / **kwargs, or redesign the API if needed
• Ensure mypy passes without suppressions
• Confirm that behavior remains correct after refactoring
