/**
 * Inline tokenizer: a markdown text run → `InlineNode[]` (nested spans).

 * Precedence (highest first): backslash escapes, plugin inline extensions
 * (trigger-char gated), backtick code spans, images, links, angle/bare
 * autolinks, then emphasis (`**`/`__` strong, `*`/`_` em, `~~` del) resolved
 * with a delimiter-run stack, then hard breaks, then text.
 *
 * Robustness for streaming: any unmatched construct at the tail (a lone `**`,
 * a half-open `[text](`, an unterminated code span) degrades to literal text.
 * The function never throws.
