v0.1.33

• Collect older completed request and response dispatchers in node-direct
  before their retained metadata exhausts the sidecar heap. The new collector
  targets 512 completed requests and preserves in-flight requests, active
  protocol operations and objects under construction, subject to upstream
  dispatcher limits. The 64 MiB old-space limit is unchanged.
• Add a 41-cycle network-heavy MCP regression that reproduced the OOM before
  the change and passes in headless and headful mode afterward.
• Refresh the full and alternating 100-site Go/Python benchmark evidence.

The authenticated Amazon workflow completed 41 pages without OOM after the
change. Pointer stalls still required keyboard controls, and retained object
counts still grew. Those limitations remain under investigation.
