Each DTO now owns its own parsing logic via fromRequest(), removing
the normalization layer from MicropubRequest entirely. UpdateHandler
gains delete support and allows replace/add/delete to compose in a
single request rather than being mutually exclusive.

Each handler now declares the data class it needs via dataClass(). The
controller builds the appropriate typed DTO from the raw request array
before calling handle(), giving handlers typed property access instead
of raw array lookups.
Handlers moved to App\Services\Micropub\Handlers, data objects to
App\Services\Micropub\Data. MicropubHandlerRegistry and the interface
are documented with flow diagrams and guidance for adding new types.
