The map stopped nesting after a fixed 3 levels, so at / a chain like
mnt/raid/media used the whole budget on full-size wrappers and showed
empty boxes with only titles. Single-child directory chains now collapse
into one label, nesting depth is bounded by block size instead of a fixed
cap, and nested blocks show size and percentage of their parent.
Declare the snapshot format (v1) stable, bump the version, ship the man
page in release archives and deb/rpm/apk/Arch packages, add a Homebrew
formula template with make brew-formula, and update the changelog,
roadmap, README and development notes.
