- stops after artifacts-reduced and adds kernels.ndjson and uboots.njdson via jq
- if one runs `./compile.sh inventory-artifacts` we shall get:
- `output/info/kernels.ndjson`: one line for each kernel build
- `output/info/uboots.ndjson`: one line for each u-boot build
- this is meant as base for other tooling that acts "for each kernel" or "for each u-boot" such as patch/config rewrites, etc
- cli-jsoninfo: better kernels.ndjson; new kernels-duplicate-config.json
- so we can detect mistakes ref LINUXCONFIG
- maybe one day the "Rewrite Kernel Config" GHA can re-use kernels.ndjson
- previous commit introduced targets-all-kernels.yaml, so one can run
- `./compile.sh inventory-artifacts TARGETS_TEMPLATE=targets-all-kernels.yaml`
