Safari and other browsers require Accept-Ranges: bytes and 206 Partial
Content responses to play video. Without this, large videos fail to load
(especially in Safari) because the entire file had to buffer in memory
before sending.
- Replace readFile + Buffer with createReadStream for efficient streaming
- Parse Range header (start-end, start-, and suffix -N forms)
- Return 206 Partial Content with Content-Range for range requests
- Return 416 Range Not Satisfiable for out-of-bounds ranges
- Add Accept-Ranges: bytes to all raw file responses

- Set up package.json (ESM, scripts), tsconfig.json, vitest.config.ts
- Install runtime and dev dependencies
- Add CLAUDE.md with architecture notes and code quality rules
- Config module with env var parsing and JWT_SECRET validation
- DB schema: users + files tables with FK cascade
- DB queries: createUser, getUserBy*, createFile, getFileById, getFilesByUserId, deleteFile
- Tests for config, db/users, db/files (15 tests passing)
