feat(scripts): migrate to TypeScript-only service scripts

- Replace dev.sh with dev.ts (starts services + CLI, stops all on Ctrl+C)
- Rewrite start-services.ts to directly start db/studio/sdk/web
- stop-services.ts kills by port (worktree-safe)
- Add CODEBUFF_SKIP_ENV_CLEAR flag for TS scripts to preserve env vars
- Remove bash dependencies entirely
