- Remove inner loop from CalcAndEncode_DeviceInfoResponse_Fresh to match
SensorStateResponse_Fresh — both now measure single alloc+encode per
iteration as intended for heap allocation cost benchmarking
- Add comments documenting why _Fresh variants skip inner loops
- Add first-wins comment to load_component_yaml_configs
- Clean up .gitignore template comment
Add automated benchmarks using Google Benchmark to prevent performance
regressions in the API protobuf encoding/decoding and core loop paths.
Benchmarks cover:
- Protobuf encode: SensorState, BinarySensorState, HelloResponse,
LightState, DeviceInfoResponse (20 nested devices + 20 areas)
- Protobuf decode: HelloRequest, SwitchCommand, LightCommand
- Protobuf calculate_size and full calc+encode send path
- Varint parse/encode/size for various value ranges
- Scheduler call/next_schedule_in with idle and active timers
- Application loop component dispatch and blocking guard overhead
Infrastructure:
- Extract shared build logic from cpp_unit_test.py into test_helpers.py
- Add cpp_benchmark.py mirroring the unit test build pattern
- Support benchmark.yaml per component dir for declaring dependencies
- Add CodSpeed CI workflow triggered on api/core changes
- Fix ProtoMessage protected destructor on host platform
