Add support for "jump to declaration", "find references", type information on hover. This support is strictly single-file for now; only references and declarations within the same file are found. We could go a bit beyond that, but to properly handle cross-file references we'll need to build an index and a compilation database, which is beyond the scope of this change. On hover, we provide the type information for the instruction under the cursor as-is. This is frequently not very useful, as the type of a function F is simply "<type of F>", but is a starting point for richer information. Assisted-by: Claude Code
