fix(tanko): adapter fixes, event logging, platform-based deploy.sh

- adapter.py: add import asyncio, use Client(site=) for Python 3.13 compat
- adapter.py: use asyncio.new_event_loop() in background thread
- adapter.py: add print() in _process_event for journald visibility
- deploy.sh: refactor to PLATFORM-based maps instead of per-agent duplications
- deploy.sh: remove backslash artifacts, deduplicate service/plugin path logic
