lsp: Add graindoc code action. over 1 year ago

AI Summary: Implement a code action in the Grain Language Server Protocol (LSP) to automatically generate a Graindoc header (similar to JSDoc) for functions when the user hovers over them. This involves modifying the source tree to expose binds and their export status, and deciding which attributes (parameters, return values, examples, since) to include in the generated header.

Complexity: 3/5
