Agents now treat pages_project_id as the stable anchor and fetch the
control-plane active package via project latest APIs, so activating a
deployment updates edges without republishing main config. Local roots use
projects/{id}/current, only the newest release is retained after a successful
switch, hash/package races retry, and per-project failures no longer block
siblings.
Make Pages package size and history retention system-configurable, support
zip/tar.gz/tar.xz/tar.bz2/tar/7z uploads, prune history with clear keep-N
semantics, and rebind agent config to the live active Pages deployment so
main-config rollback never depends on pruned packages.
