feat: add Telegram playbook notifications (issue #81)

- notify_playbook_generated(): market, stock/scenario count, token usage (MEDIUM)
- notify_scenario_matched(): stock, action, condition, confidence (HIGH)
- notify_playbook_failed(): market, reason with 200-char truncation (HIGH)
- 6 new tests: 3 format + 3 priority validations
