fix: rename pm2 worker and invoke tsx directly instead of npm

pm2 fork mode require()s the resolved script rather than spawning a
shell, and on o2switch `npm` resolves to CloudLinux's bash npm_wrapper,
so pm2 crashed instantly (SyntaxError) and restart-looped forever.
Point pm2 at tsx's real ESM entry (node_modules/tsx/dist/cli.mjs)
instead. Also renames the pm2 process to video-downloader-worker.
