Module key 

Vim-notation key parser.

Parses strings like <C-w>v, gT, <leader>fa, <C-S-Tab> into a list of KeyChords the page-mode dispatcher can match against.

Notation supported:

• <C-...> — Ctrl
• <S-...> — Shift (also implied by uppercase ASCII letters when bare)
• <M-...> / <A-...> — Alt / Meta
• <D-...> — Super (Cmd on macOS)
• <leader> — abstract placeholder; resolution to a concrete char happens at trie-build time, not here.
• <Space>, <Esc>, <CR> / <Enter>, <BS> / <Backspace>, <Tab>, <S-Tab> / <BackTab>, <Up>, <Down>, <Left>, <Right>, <Home>, <End>, <PageUp>, <PageDown>, <Insert>, <Delete>, <F1>–<F12>
• Bare characters, including punctuation: g, T, ,, ;, :, /, ?, < (escaped as <lt>).

Whitespace in the input is ignored. Empty input yields an empty Vec. Embedded literals like Hello parse as five separate chords (one per char) — this parser is not a string-mode parser.
