Move ai-stack and paintplus vendored source under vendor/

Matches the existing vendor/easy-asterisk convention (used by services/asterisk.sh) instead of two one-off top-level directories that cluttered the repo root and didn't look like anything else next to setup.sh, lib/, services/, extras/. Only the two services' own SRC_DIR path resolution and header comments needed updating — nothing else in the repo referenced the old ./ai-stack / ./paintplus paths. Also documents vendor/ in README.md's Layout section.
