The test-grouping pipeline merged components that share a bus signature
into a single config without checking CONFLICTS_WITH. When
bme68x_bsec2 declared CONFLICTS_WITH=["bme680_bsec"] (and vice versa),
the merged YAML containing both failed validation.
Statically parse AUTO_LOAD and CONFLICTS_WITH from every component
__init__.py, propagate conflicts through AUTO_LOAD, and split any
group that contains a conflicting pair into separate builds.
