Deserialize a dynamic handler's raw wire arguments into a typed value T.
The UDA-driven registration overloads marshal each argument from the method
signature for you, but the dynamic registerDynamicTool/registerDynamicPrompt
overloads hand the handler the raw Json arguments. This is the inbound
counterpart of the client's callTool!T: it deserializes arguments through
the same enum-by-name policy the UDA layer uses (so any enum leaf is read
from its schema-declared member name, at any nesting depth) and maps a vibe
conversion failure to invalidParams (-32602), matching how the reflection
layer reports a malformed argument. A handler can then write
auto a = argsAs!MyArgs(arguments); instead of hand-rolling
arguments["x"].get!int with manual presence/type checks.
