@W-23751548: Preserve release archive artifacts

[mlischetti]

Summary

• retain single-file CLI ZIP and Python wheel CI artifacts using archive: false
• download CLI ZIPs and Python wheels without decompression
• download artifact categories separately and only publish archives plus native-library files
• fail the matrix build if a CLI ZIP or Python wheel is missing
• remove the unused Python TCK JUnit report generation and upload

Root Cause

The publisher downloaded every artifact and allowed download-artifact@v8 to decompress CLI ZIP payloads. The broad regular-file scan then sent CLI internals, such as ndjson-module-2.12.2.jar, to the GitHub Release.

Verification

• python3 -m pytest native-lib/python/tests/unit/test_ci_structure.py
• Python YAML parsing for all changed Actions YAML files
• git diff --check
• Read-only code review: no findings
