refactor: modernize codebase for Go 1.26 and fix adapter issues

- Upgrade Go version from 1.24 to 1.26.1 with updated dependencies
- Replace interface{} with any type throughout codebase
- Add message deduplication in OneBot11 adapter to prevent duplicate event processing
- URL-encode access token in WebSocket connections to handle special characters
- Remove duplicate bot startup hooks in DI providers (now handled by botManager.StartAll)
- Use slices.Clone and errgroup.Go patterns for cleaner concurrent code
- Apply omitzero JSON tags for optional fields (Go 1.24+ feature)
