refactor: flat artifacts via archive:false, skip-decompress, parse zip names (#136)

Changes in action.yml:
- Create Kernel ZIP: mv metadata txt from ARTIFACTS_FOLDER to AK3_FOLDER before zip creation so it's included in AK3 zip
- find -delete: removed obsolete txt exclusion
- Upload Artifacts: name set to ZIP_NAME, path changed to exact zip file, added archive: false to prevent container wrapping
- Final Build Summary: added Artifact Name row to both GITHUB_STEP_SUMMARY and summary.txt

Changes in build-kernel-release.yml:
-Download Artifacts: replaced download-artifact v4 with v8 using merge-multiple and skip-decompress to get all files flat
-matrix.json path updated from build-matrix/matrix.json to matrix.json (flat)
-Release notes loop: replaced txt-based parsing with zip filename parsing
-Upload assets loop: simplified from /.zip to *.zip flat
-Release summary: Kernels count and Assets loop updated to use flat *.zip pattern with maxdepth 1
