Function parseAttributes

parseAttributes(
ctx: ParseContext,
startPos: number,
): { attrs: Record<string, string>; consumed: number }
Parses HTML-style attributes from block opening tags.

Supports:
- name="value" (quoted string)
- name=value (unquoted single-token value)
- name (boolean attribute, stored as "true")
- Hyphenated names like data-paragraph or aria-label (composed from TEXT - IDENTIFIER token sequences).
Attribute names are lowercased (Wikidot is case-insensitive). The result is filtered through filterUnsafeAttributes to strip potentially dangerous attributes (e.g. onload, onclick).

Stops at BLOCK_CLOSE, NEWLINE, or EOF.
Parameters
- ctx: ParseContext
  Parse context.
- startPos: number
  Token index to begin scanning.
Returns { attrs: Record<string, string>; consumed: number }
Parsed (filtered) attributes and total tokens consumed.
