Summary

• Discover repositories accessible to GH_ACTIVITY_TOKEN automatically using the authenticated user's repository list, with pagination.
• Keep GH_ACTIVITY_REPOS as an optional additive override rather than a required list.
• Include a repository only when it has at least one commit in the previous 24 hours; quiet repositories are skipped even if they had a PR or release.
• Record commit SHA, message, author, timestamp, repository description/language/default branch, and related merged PRs/releases.
• Add unit coverage for discovery pagination, quiet-day skipping, and activity rendering.
• Update README and the interactive manual with the actual token requirements.

Required setup

Add a fine-grained personal access token as the GH_ACTIVITY_TOKEN Actions secret, granting read-only Contents, Pull requests, and Metadata access to the repositories to scan. The daily workflow already passes this secret to the collector.
