…-size limits The maxMsgSize, maxCredentialCountInList and maxCredentialIdLength fields from authenticatorGetInfo were parsed but never read. Enforce them before sending make-credential and get-assertion requests on both the preflight and non-preflight paths so cable is covered. Drop allow and exclude entries whose id exceeds maxCredentialIdLength, reject lists over maxCredentialCountInList, and bound the serialized request by maxMsgSize using the 1024-byte default when the field is absent. A new PlatformError::RequestTooLarge surfaces these cases instead of relying on the authenticator CTAP status.

Authenticators report size and credential-list limits that the client did not act on, so oversized requests failed at the device with opaque errors. This keeps requests within the reported message size, drops credential ids too long to belong to the device, and reports an over-count list clearly. The checks run on both the preflight and direct paths.
Closes #254.
