/**
 * Preprocessor to normalize malformed GFM table separator syntax.
 *
 * Fixes the common mistake where the alignment colon is placed after the pipe
 * instead of before the dashes:
 *
 * Invalid: `|: ---` or `|:---` (colon after pipe)
 * Valid:   `| :---` (colon before dashes)
 *
 * Also handles right alignment:
 * Invalid: `| ---:| ` with space before pipe
 * Valid:   `| ---:|` (no space before closing pipe)
 *
 * This runs before remark-parse to ensure the table is recognized as a valid GFM table.
