fix(tui): input wrap width mismatch — last letter no longer flickers

Browse source 
The 'columns' prop passed to TextInput was cols - pw, but the actual
render width is cols - pw - 2 (NoSelect's paddingX={1} on each side
subtracts two cols from the composer area). cursorLayout thought it
had two extra cols, so wrap-ansi wrapped at render col N while the
declared cursor sat at col N+2 on the same row. The render and the
declared cursor disagreed right at the wrap boundary — the last
letter of a sentence spanning two lines flickered in/out as each
keystroke flipped which cell the cursor claimed.

Also polish the /help hotkeys panel — the !cmd / {!cmd} placeholders
read as literal commands to type, so show them with angle-bracket
syntax and a concrete example (blitz row 5 sub-item 4).
