Correct fix — slsa_level 0 is valid for software-only Level 0 records per the TRACE spec. Minor: spaces after commas in the frozenset and error message string, but not blocking. Merging.

v0.2 added support for slsa_level: 0 (software-only platforms, no hardware attestation), but the schema, tr_sca.py, and the test suite were never updated to match — so a valid Level 0 record currently gets rejected.
This PR fixes that:
Didn't need to touch test_level0_negative.py — it already checks that 4 and -1 get rejected, and this change doesn't affect either bound, just adds 0 as a new valid floor.
