Add Docker support with Dockerfile and docker-compose.yml, update build scripts and README for containerized deployment.

- Updated server `Bun.build` configuration: adjusted `outdir`, added `format` as `esm`, and set `@open-gsio/client` to external.
- Expanded README with Docker instructions.
- Added new package `@open-gsio/analytics-worker`.
- Upgraded dependencies (`vite`, `typescript`, `bun`) and locked `pnpm` version in `package.json`.
