-- All PRs with information about failed tests in PR-check.
--
-- Logic:
--   1. Take all PRs from github_data/pull_requests (deduplicate by latest exported_at).
--   2. For each PR and build_type find the latest PR-check run within $test_lookback_days days.
--      relwithdebinfo and release-asan are tracked separately (same workflow run_id / job_id
--      is shared across matrix jobs, so build_type must be in all aggregations).
--   3. Determine if PR is blocked by tests (per build_type):
--      - is_pr_blocked_by_tests_in_last_run_and_try = 1 if the latest run
--        has failures on the third attempt (attempt = 3).
--      - Third attempt is final; if a test failed there, PR is blocked for that build_type.
--   4. LEFT JOIN to detailed info for each failed test:
--      full_name, job_id, branch, logs, owners, etc.
--
-- Result: one row per (PR, build_type, failed test) pair. PRs with no failures are included
-- (with empty test fields) per build_type that had a PR-check run.
--
-- Parameters:
--   $test_lookback_days — test selection window (days). Limits scanning of
--     test_runs_column. PRs with tests older than this period are excluded.
--     Default 65 ≈ 2 months (buffer for long-lived PRs).
