Subject: [PATCH] fix: ensure output dirs exist in extract and API extract
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

cmdExtract and handleAPIExtract were missing os.MkdirAll calls
while cmdDownload, cmdPipeline, and handleAPIDownload all had
them. The bash script creates dirs internally but this is not
robust — create dirs in Go before shelling out.

Closes #13
