d9fb88f530Implement steps 1 + 2 of issue #115: turn recorded build failures into triaged patch suggestions instead of hand-scraping Crow logs. - add local/failing-builds-classify.R with pure, DB-free helpers to normalise error_text into a stable fingerprint and classify it against a seed signature set (removed tbb_stddef.h, RcppParallel bundled TBB, system libuv link leak), each carrying a fix tier, confidence, and an auto/human-only flag - add local/failing-builds-report.R, a read-only entrypoint that queries single_builds WHERE error_occurred, groups by root cause, classifies each group, and prints (optionally emits JSON) a triaged report with a pre-filled registry.json entry for known, safe fix levers only - keep novel source diffs and unknown signatures routed to human triage, per the issue guardrails; never write to the DB or the registry - cover the helpers with local/tests/test-failing-builds-classify.R and document the workflow in local/patches/README.md
