Review Comment:
   `Provider.MaxFrameSize` is an `int` coming from URI options and can be set 
to a negative value; casting a negative `int` to `uint` will produce a huge 
frame size and can break protocol negotiation. Guard against non-positive 
values before assigning `Open.MaxFrameSize`.

Review Comment:
   `NmsConnectionInfo` is a public type; removing `ChannelMax`, `MaxFrameSize`, 
and `IdleTimeOut` is a source/binary breaking change for any consumers that 
used these properties. Consider reintroducing them as `[Obsolete]` shims (even 
if the provider now owns the values) to preserve compatibility for the 2.x line.
