Dead code: extractRunNumber always returns -1

[that-github-user]

Description

extractRunNumber in src/commands/list.ts:18-20 always returns -1:

export function extractRunNumber(_filename: string): number {
  return -1; // Assigned by loadAllRuns based on sort position
}

Run numbers are actually assigned by loadAllRuns() using array index (buildRunSummary(i + 1, r.result)), making this function dead code. It's only imported in list.test.ts.

Suggested fix

Remove extractRunNumber entirely and update its tests. If filename-based extraction is needed in the future, implement it properly at that time.

Fixed in #148. Removed dead extractRunNumber function.
