[Narada Code 6] Add Python project sync workbench CLI

[xTRam1]

Summary

Adds the M6 Agent Maker Workbench bridge for multi-file local Python APA projects:

• narada workbench studio sync-python-project packages a local project into today's single-file Agent Studio pythonAgent runtime item.
• project-diff compares local project state against the embedded remote source manifest.
• project-export reconstructs source files from a generated runtime item.
• Source scanning rejects unsafe files, symlinks, binaries, hidden/generated files, path escapes, and oversize bundles.
• Generated runtime uses a base64+gzip source bundle plus temp-dir extraction and runpy.run_path, preserving ordinary imports without a flat compiler.
• Proof-root artifacts, command-ledger rows, redaction behavior, guarded updates, non-empty export safety, and tests are included.
