Add cowsay-style /bin/baresay and identical /bin/say (say maps to baresay

source via build.mjs). Ship lib/baresay-engine.js for wrapping, balloons,
and cowfile parsing; default character is bear under /share/baresay/.cow.

Register commands, man pages, rebuild man/completion/posix index, sync
kernel to seeder, bump Tier-1 command count in docs to 155, and add a
test that say and baresay bundles match.
