Description

Given a file called foo.gleam, (module name foo), and lots of other modules that have import foo and also call foo.stuff().

When foo.gleam gets renamed, we can give the user a choice to auto-rename all references and imports.

We may also want to have a rename module code action when on top of a module reference or import, which would need to also rename the file.

Research direction
Investigate the current LSP implementation in the Gleam compiler, specifically the 'gleam lsp' crate. Look at how existing code actions (like 'Rename Symbol') are implemented, especially the handling of file system changes. The issue mentions that renaming a module should also update all imports and file references. Start by examining the 'rename' module in the LSP and understand how module references are tracked. Additionally, review the comments on the issue for any implementation suggestions or concerns.
