Subject: [PATCH 2/6] fix: resolve subshell variable scoping in validators

- Fix validate-a2ml.sh, validate-bot-directives.sh, validate-k9.sh,
  validate-permissions.sh, validate-sha-pins.sh, validate-spdx-workflows.sh
  to use heredoc/process substitution instead of pipes for while loops
- This ensures ERRORS variable updates are visible outside the loop
- Fix pre-push hook to pass INPUT_STAGED_FILES to validators

Subject: [PATCH 4/6] fix: resolve Hypatia and baseline test failures

- Fix hypatia-scan-reusable.yml: remove -s flag from jq validation, simplify to expect flat array of findings
- Fix apply-baseline.sh: treat unknown severities as critical (rank 5) instead of 0 for fail-safe behavior
- Fix science-ci-security-test.rb: use correct flat array format and valid severities

These changes resolve the Self Test failures related to Hypatia validation.

Subject: [PATCH 5/6] fix: resolve remaining test failures from TASK 3

- Fix hypatia-scan-reusable.yml: restore -s flag to jq validation to properly
  handle empty arrays [] (no findings) while still rejecting multiple JSON
  documents. This fixes the 'empty findings are valid' test in hypatia-blocking-gate-test.sh.
- Fix science-ci-security-test.rb: change test from '[]' to '[] []' to test
  multiple JSON documents instead of single empty array.
- Fix check-workflows-parse.sh: add has_no_jobs() check to reject workflows with
  no jobs (comment-only workflows), which fixes the policy-gates-test.sh failure.
- Restore scripts/check-descriptile-policy.sh: was missing from repo but referenced by
  science-ci-security-test.rb.

These changes resolve the 2 remaining test failures (policy checker, debt ratchet)
mentioned in the estate audit.

Subject: [PATCH 6/6] fix: handle grep failures in validate-spdx-workflows.sh
 with set -e

- Change grep check from compound command to if statement to prevent
  script exit on grep non-match under set -e
- This fixes the validator when checking workflow files with SPDX headers
