astro build resolves the public/data symlink and copies all activity JSON
into dist/; rsync then copied that to the webroot — but nginx already serves
/data/ directly from /var/bincio/data/ via alias, so both copies were dead
weight. Freed 36 GB → 14 GB on the live server.
- post-receive hook: prune dist/data/ before rsync, add --exclude=data/
- docs: update manual rebuild command and nginx comment to match
- serve/server.py: _mb() now uses lstat() to count symlinks at face value
rather than following them to targets, so admin storage panel no longer
double-counts _merged/ (which is mostly symlinks into activities/)
