Add per-operation hooks to GraphQLHandler

The handler already exposes pre/post hooks per plan step, but nothing runs
once per operation, and the response payload is assembled entirely inside
executeRequest. Users who need to touch the payload, e.g. to add response
extensions gathered during execution, had to reimplement the handler.

WithPreOperationHook runs after the RequestContext is built and before
planning; it may replace rc.Context, which is how per-operation state
reaches the executor and the queryers even in batch mode, where every
operation otherwise shares the incoming request context.

WithPostOperationHook runs as the last step before the operation's payload
is written, on success and on failure. It sees the payload exactly as the
gateway would have written it, including the gateway's own extensions, and
may add or modify keys. The gateway itself makes no assumptions about what
the hook does with them.
