#9295 Work with dune 3.25

dune 3.25.0 (released 2026-11-12) gives an executable its public name in dune describe workspace, so the license check found none of the shipped executables; it now accepts either name. ocaml-lsp-server 1.27.0, which the lsp pin holds the dev setup to, doesn't build against stdune 3.25, so the dev setup keeps stdune below it.

lsp was pinned to 1.27.0 because 1.28 added snippet text edits, which the analysis CLI's edit printing didn't accept; it prints them now. lsp and jsonrpc move to 1.28.1, so the dev setup gets ocaml-lsp-server 1.28.1 instead of 1.27.0, and the stdune bound for it goes.
