fix(tooling): only log rejections when all attempts exhausted (#833)

Individual dedup/blocklist/placeholder/empty rejections that recover
on the next attempt are now silent. Only the skipped: summary line
prints when all 5 attempts fail. Subprocess errors still print
immediately (those indicate a real problem).
