Version 0.26.2

Fixed

• Query, header, and cookie parameter casting now handles repeated values correctly, preserving list-style inputs instead of nesting them.
• Parameter casting now supports typed collection casts such as list[str], dict[str, int], and nested union collections like list[str | int | dict[str, str]].
• cast=list now treats a single string value as a one-item list instead of splitting it into characters.
• Default parameter values are now passed through their configured cast when applicable.
