New proposals: slices.Move and doc links to instantiated types

Two proposals lead the list. One adds a slices.Move primitive to replace the common two-memmove idiom for relocating an element, the other extends go/doc/comment so documentation can link to instantiated generic types. On the discussion side, a piece on socket options that matter in high-performance Go networking is the most substantive thing in the thread pile, alongside a blog post arguing the Go language server is quietly very good at code navigation.
