Function appendEditionQualifier

appendEditionQualifier(
    seoTitle: string,
    runId: string,
    titleBudget?: number,
): string
Post-clamping cross-run title uniqueness. Appends a compact edition qualifier (#N) to the resolved SEO title when a run number is extractable from the run ID. This runs AFTER clampForBudget so the qualifier is never truncated by the per-script budget clamper.

The compact form (#N) is used (universal publishing issue-number convention) because it adds only 4-5 chars and survives even the tightest RTL/CJK budgets.

Budget-aware: the qualifier is only appended when the resulting title fits within the per-script title budget. Otherwise the title is returned unchanged to preserve SERP-optimal length.
Parameters
- seoTitle: string
  Resolved, clamped SEO title
- runId: string
  Workflow run identifier (e.g. "run-52", "breaking-run170")
- OptionaltitleBudget: number
  Optional per-script title budget; when provided, the qualifier is only appended if the result fits within budget
Returns string
Title with edition qualifier appended for uniqueness
