debug: add gc-client TODO rm before merge

add automatic add and cat for debugging purposes

retry cats

cast string

argh! @whyrusleepgin

use mock repo to avoid clashing

larger files for more variety FIXUP into gc-client

fix: change in both places FIXUP gc-client

 fix(gc-client) start with size 1 (unit)

fix(gc-client) start at 1 FIXUP prev

gc-client rm comment

gc-client larger files

fix(gc-client) cat the data out to dev null to ensure entire file is fetched

perf(gc-client) use io.Pipe to handle io transfer
