EDEN 100.99.56 validation report

Implemented:
- Registered group/channel delete confirmation now explicitly warns that Telegram leaveChat will be attempted.
- Confirmation callback calls managedChatRemoveAndLeave().
- leaveChat is called using the stored Telegram chat ID.
- Active references are cleaned before the managed destination row is deleted.
- Success and already-not-a-member outcomes are marked as not current in bot_chat_registry.
- On an unconfirmed leave, the destination is still removed from registered lists and the current-membership record plus Telegram error is retained so owner can retry from the bot-presence page.
- PHP lint: PASS; 81 PHP files with no syntax errors.
- update.json: PASS; version and release are 100.99.56.
- Release manifest paths: checked during packaging.
- Live Telegram Bot API / cPanel DB integration: NOT RUN.
