Implements a Language Server Protocol server for El files over stdin/stdout JSON-RPC. Provides completions (builtins + keywords + document functions), hover documentation, go-to-definition, and full document sync. Also adds a VSCode extension that launches the binary as a child process and a TextMate grammar for .el syntax highlighting. NOTE: el-lsp.el calls __read_n(n: Int) -> String, a seed primitive not yet in el_runtime.c. Build.sh documents the required C implementation; the seed agent must add it before the binary will link.
