chore: clean up debug files and update workspace dependencies

Remove temporary debug and testing files from repository:
- Remove debug-binary-constructor.js, debug-binary-deep.js
- Remove debug-hex-dump.js, debug-npm.js
- Remove old package tarball pulseengine-studio-mcp-server-0.2.5.tgz

Update workspace to use PulseEngine MCP 0.7.0 dependencies
with commented macro reference for future integration.

These changes clean up the repository and align with the
production-ready v0.2.15 release status.
