Function socket_path 

pub fn socket_path(workspace_root: &Path, language: LanguageId) -> PathBuf

Generate a deterministic Unix socket path for a workspace and language.

The path is derived from a SHA-256 hash of the canonical workspace root, combined with the language server identity (not the language itself – languages sharing a server get the same socket).

Path format

{socket_dir}/lsp-{server}-{hash}.sock

Where socket_dir is $XDG_RUNTIME_DIR/aether-lspd if available, or /tmp/aether-lspd-{uid} otherwise. The UID suffix prevents permission conflicts between users on shared machines.
