Restructure repository: organize blueprints into folders

Each blueprint now has its own folder containing:
- blueprint.yaml: The automation code with a short header
- README.md: Detailed documentation extracted from headers

Updated CLAUDE.md with repository structure guidelines.

+# Thermostat Controller Blueprint
+
+This blueprint controls a thermostat/climate entity based on schedules, presence, and various conditions.
+
+## Features
+
+- Schedule-based heating control (using HA schedule helper)
+- Working and standby temperature modes
+- Optional input_number overrides for temperatures
+- External temperature sensor support
+- Window/door sensor integration (disable when open)
+- Force heating override
+- Minimum on-time to prevent rapid cycling
+- Configurable behavior when disabled (off vs standby)
+- Debug notifications for troubleshooting
+
+## Temperature Priority
+
