 /**
  * Loads and parses a .geminiignore file from the given workspace root.
- * The .geminiignore file follows a format similar to .gitignore:
- * - Each line specifies a glob pattern.
- * - Lines are trimmed of leading and trailing whitespace.
- * - Blank lines (after trimming) are ignored.
- * - Lines starting with a pound sign (#) (after trimming) are treated as comments and ignored.
- * - Patterns are case-sensitive and follow standard glob syntax.
- * - If a # character appears elsewhere in a line (not at the start after trimming),
- *   it is considered part of the glob pattern.
+ * The .geminiignore file follows a format similar to .gitignore.
  *
  * @param workspaceRoot The absolute path to the workspace root where the .geminiignore file is expected.
  * @returns An array of glob patterns extracted from the .geminiignore file. Returns an empty array
  *          if the file does not exist or contains no valid patterns.
