Function validateBlock

validateBlock(
    block: Block,
    rules?: ResolvedRules,
    index?: SuppressionIndex,
): Promise<ValidationResult>
Validate an extracted Block end to end: structural checks (unclosed / empty fence), semantic warnings, then the fast Rust (merman) parser with a mermaid.js fallback for anything merman rejects. mermaid.js is treated as authoritative on the final verdict.

Bodies that fail mermanVerdictIsTrustworthy skip the fast path and always consult mermaid.js, because merman claims to accept input it never really parsed.
Parameters
- block: Block
  The block to validate.
- rules: ResolvedRules = RULE_DEFAULTS
  Resolved per-rule severities for the semantic pass. Defaults to RULE_DEFAULTS.
- Optionalindex: SuppressionIndex
  Suppression index to consult for semantic findings. Forwarded to checkSemantics.
Returns Promise<ValidationResult>
A ValidationResult carrying the verdict and any warnings.
