🔥 JSON info pipeline: v18

- pipeline: add `pipeline` context object to targets; use it to filter artifacts and images to build; warn about oci-name with multiple oci-tags - pipeline: better error messages when info's fail; show some (out-of-order) progress messages during parallel info gathering - pipeline: targets-compositor: add `not-eos` inventory - TARGETS_FILENAME, log all OCI lookups - SKIP_IMAGES - IMAGES_ONLY_OUTDATED_ARTIFACTS - no dash in chunk id in JSON - pipeline: very initial chunking, using the same outputs - pipeline: template targets, `items-from-inventory:` inventory expansion, CHECK_OCI=yes, CLEAN_MATRIX=yes, CLEAN_INFO=yes, many fixes - cli: `inventory` / `targets` / `matrix` / `workflow` - pipeline: workflow beginnings - pipeline: general log cleanup + OCI stats / better miss handling - pipeline: fixes/reorg - pipeline: catch & log JSON parsing errors - pipeline: gha matrix: use IMAGE_FILE_ID as job description - pipeline (delusion): gha workflow output, based on old matrix code - pipeline: better parsing and reporting of stderr log lines (under `ANSI_COLOR=none`) - pipeline: mapper-oci-uptodate: use separate positive/negative cache dirs (GHA will only cache positives); cache negs for 5 minutes locally - pipeline: output-gha-matrix artifacts + images - pipeline: output-gha-matrix artifacts + images: "really" and fake 1-item matrix if empty - pipeline: move files into subdir; update copyright & cleanup - pipeline: refactor bash jsoninfo driver a bit - pipeline: outdated-artifact-image-reducer - pipeline: introduce `target_id` at the compositor, aggregate it at the reducer, carry it over in the artifact info mapper - pipeline: mapper-oci-uptodate - pipeline: info-gatherer-artifact, with PRE_PREPARED_HOST - pipeline: refactor/rename info-gatherer-image.py - pipeline: beginnings
