ci: restrict uploaded artifacts to release and test evidence

[Quaternion8192]

Replace recursive artifact-directory uploads with file allowlists so verification caches, consumer bin/obj output, published executables and ABI build intermediates are omitted. Retain packages and symbols, manifests, SBOMs, release/support notes, consumer project/source and lock files, and test/verification reports across CI, preview and stable evidence.

Only upload path fields in three workflows change. All verification commands, publication steps, artifact names, retention and failure policies remain identical to develop.

Verification

• YAML parsing and structural comparison passed: every non-path workflow field is unchanged.
• All 10 upload allowlists passed fixture checks using the GitHub Actions glob library, including required evidence and rejected cache/binary/temporary files.
• git diff --check passed; one atomic commit; default Quaternion8192 author and committer.
• No library source or dependencies changed. Validation tooling and fixtures are ignored under draft.
