Prevent memory writer starvation and release 1.14.1 - #8

Conversation
Windows sustained contention exposed writer starvation after the snapshot upgrade fix. Share a FIFO gate across handles of the same database, acquire it before a connection, and use it for memory, learning, and passive usage transactions. Keep reads available and retain weak references only while handles are alive. Exercise independent handles and read availability under a held writer, repeat contention tests on Windows CI, and advance desktop and core to 1.14.1. The unpublished 1.14.0 draft remains withheld.
