feat: add desktop cleanup, manual demo tools, and fix trainer OOM bugs (#195)
- Add clean_desktop() to WAADirect to kill known distracting apps between episodes, preventing stale desktop state from leaking across phases - Handle close_all config entry type in WAADirect.setup_task() - Create manual notepad-hello demo (DemoLibrary-compatible, no screenshots) - Add scripts/create_manual_demo.py CLI for authoring demos from text specs - Fix vision tensor exclusion in GRPO loss computation (OOM on L40S) - Add try/except for float parsing in parse_vlm_output_to_action - Lower max_new_tokens default from 2048 to 512 (prevents OOM, sufficient for Thought+Action format) Co-authored-by: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
