Parse `let mapleader` directives and substitute `<leader>` in mapping commands before passing lines to CodeMirror's handleEx(). This is pure text substitution at the plugin level — no CodeMirror changes needed. - Default leader is `\` (backslash), matching Vim - Case-insensitive: <leader>, <Leader>, <LEADER> all work - Single-pass processing: each `let mapleader` affects subsequent mappings only - Only substitutes in recognized mapping commands (no false positives) - Backwards compatible: no change for users who don't use <leader> - Works with `source` command (sourced files inherit/override leader) Closes esm7#117
