- Add --output-format stream-json to runPrompt() for JSON output with token usage data - Add parseTokensFromStatusLine() to parse tokens from Claude's status line display in interactive mode (e.g., "123.4k tokens") - Token parsing supports numeric, k (thousands), and M (millions) suffixes - Estimates input/output split (60/40) for interactive mode since only total is displayed Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
