/**
 * LaTeX delimiter normalization for Feishu upload.
 *
 * lark-cli's markdown parser applies italic parsing to _ inside math delimiters
 * ($, $$, <equation>), breaking multi-subscript formulas.
 *
 * Fix: insert \mkern0mu between } and _ to break the italic trigger.
 * \mkern0mu is a zero-width TeX kern (renders as nothing) — it ends with the
 * letter 'u', which is a word character. Markdown italic openers require the _
 * to be preceded by a non-word char; inserting \mkern0mu ensures _ is preceded
 * by 'u' instead of '}', making it invisible to the italic parser.
 *
 * Strategy:
 *   \[...\]  →  $\mkern0mu-protected content$  (display → inline)
 *   \(...\)  →  $\mkern0mu-protected content$  (inline)
 *   $$\n...\n$$  →  $\mkern0mu-protected content$  (collapse multi-line)
 *   $...$    →  $\mkern0mu-protected content$  (protect pass-through)
 *   $$...$$ →  $$\mkern0mu-protected content$$  (protect pass-through)
