Release 0.1.1 VIP token automation and bot auth improvements

[Jamesllllllllll]

Summary

Prepare the 0.1.1 VIP-token automation release. This adds fractional VIP balances, automates Twitch-native VIP rewards for gifted subs and cheers, and tightens the bot auth/reconnect workflow needed for bot-badged chat replies and safer local testing.

What Changed

• Added fractional VIP token balances end-to-end, including redemption from partial balances, moderation editing, validation, and tests.
• Added configurable VIP token automation for gifted-sub gifters, gifted-sub recipients, and cheers, plus public playlist messaging that explains the active earning rules.
• Added EventSub support-event processing and delivery dedupe so automation events do not double-grant on redelivery.
• Updated Twitch auth/bot integration docs and release metadata for 0.1.1.
• Polished the moderation VIP token stepper so repeated clicks are allowed during debounce and controls only lock while the save request is in flight.

How To Test

1. Run npm run format.
2. Run npm run lint.
3. Run npm run typecheck.
4. Run npm run test.
5. Run npm run build.
6. In the dashboard moderation view, edit VIP balances including fractional values like 1.5, then redeem one VIP request and confirm the remaining balance is 0.5.
7. In the dashboard settings view, enable gifted-sub and cheer VIP automation, then verify the public playlist page shows the correct VIP token earning summary.
8. Trigger Twitch EventSub payloads for channel.subscription.gift, gifted channel.subscribe, and channel.cheer, then confirm tokens are granted once and bot replies are sent only when the configured threshold is met.

Screenshots Or UI Notes

• VIP token balances now support decimals in moderation.
• The public playlist page now shows a small VIP automation summary when support-based rewards are enabled.
• The moderation VIP token stepper no longer locks during the debounce window.
