fix(cli): escape Rich markup in BudgetExceededError and use stderr

Fixes critical issues in budget error handler:
- Escape exception message to prevent Rich MarkupError when str(BudgetExceededError) contains [budget] tags
- Print error to stderr to avoid corrupting JSON/JSONL structured output
- Apply budget handling to missing _run_inline_workflow call site
