delete playlist/ — committed derived output that was deploying

31 tracked files, untouched since 2026-06-11, read by no code: `track` and `journey` write a playlist.json into whatever --out you give them, and make-mix-page.js takes its directory as an argument.

• It also contradicted the repo's headline rule in public — source is committed, audio is derived and gitignored

• The .gitignore comment that kept them tracked cited "playlist/ and mix/"; mix/ has not existed for some time.
