Nightly report: post details as follow-up comments instead of truncating (#1239)

When the full report exceeds GitHub's 65K body limit, the summary
table stays in the discussion/issue body and the verbose skill/agent
output is posted as follow-up comments (split into chunks if needed).
This ensures no output is lost.
