bfs (breadth-first version of the UNIX find command)

bfs is a variant of the UNIX find command that operates breadth-first
rather than depth-first, typically locating files faster by listing
shallower paths before descending into deeper subtrees. It is mostly
compatible with POSIX, GNU, FreeBSD, OpenBSD, NetBSD, and macOS find,
and adds quality-of-life improvements like colored output, helpful
error messages, and operators such as -exclude and -hidden.

Example: searching for a config file near the top of a tree with a
huge subdirectory like node_modules:

  $ find ~/project -name 'config.json'
  (slow: descends into node_modules first)

  $ bfs ~/project -name 'config.json'
  (fast: finds shallow matches before diving deeper)
