fix: address 5 critical and major PR review issues

- Remove set -e from validate-marketplace.sh to prevent early exit on
  check failures, allowing the summary to always be displayed (PRRT_kwDOO6Hdxs5uvKrc)
- Fix marketplace.json source path to point to skills/unraid instead of
  ./ for correct plugin directory resolution (PRRT_kwDOO6Hdxs5uvKrg)
- Fix misleading trap registration comment in unraid-api-crawl.md and
  add auth note to Apollo Studio URL (PRRT_kwDOO6Hdxs5uvO2t)
- Extract duplicated cleanup-with-error-handling in main.py into
  _run_shutdown_cleanup() helper (PRRT_kwDOO6Hdxs5uvO3A)
- Add input validation to read-logs.sh to prevent GraphQL injection
  via LOG_NAME and LINES parameters (PRRT_kwDOO6Hdxs5uvKrj)
