feat(qa): package linter as publish gate + v1 full-catalog heatmap
lint_package.py checks contamination, alphabetical truncation, count
consistency, provenance completeness and intro grammar; wired into both
publish paths (p4_publish + batch stage_packages), SKIP_LINT=1 reserved
for labeled v1-grade republishes. Heatmap over 3,039 v1 packages:
1,406 clean / 1,633 with findings; C2 truncation is systemic (generator),
contamination affects 2.6% of crawled packages; nothing requires
re-fetching.
