feat: add time-based multiplier sizing, pause-after-win, and outcome-based win detection

- Time-based bet sizing multiplier (SNIPER_MULTIPLIERS, UTC+8 windows)
- Pause N rounds per asset after win (SNIPER_PAUSE_ROUNDS_AFTER_WIN)
- Win detection via payoutNumerators outcome check instead of redeem value threshold

  * Console-only entry point for the Orderbook Sniper bot.
  * Places tiny GTC BUY orders at a low price on both sides of 5-min markets.
  *
+ * Features:
+ *   - Time-based multiplier sizing (SNIPER_MULTIPLIERS, UTC+8)
+ *   - Pause N rounds per asset after a win (SNIPER_PAUSE_ROUNDS_AFTER_WIN)
+ *   - Win detection via outcome (payoutNumerators), not redeem value
+ *
  * Run with: npm run sniper       (live, console)
  *           npm run sniper-sim   (simulation, console)
