BuildKit Builds & SDK Performance

This release improves the sandbox build system by switching to BuildKit, bringing faster parallel builds, better layer caching, and heredoc support for custom sandbox images. TypeScript packages are also renamed from @daytonaio/* to @daytona/*, with dual-publish ensuring backward compatibility.

SDK performance receives a major fix: log demultiplexing in the Python and Ruby SDKs was scaling quadratically, blocking execution on large outputs. The rewrite is 77x faster on 5 MB logs. The Python SDK also fixes async file downloads failing when multipart headers spanned chunk boundaries.

Additional fixes address the computer-use scroll action hanging indefinitely and a daemon WebSocket write mutex issue.
