OpenReflex 0.5.1

Fixes found by a local QA pass of the released 0.5.0 package.

• A WAITING execution now resumes on the next prompt for that session even when the text is not byte-identical to
  the original, instead of being silently finalized as unknown.
• A trivial zero-tool response (for example a single character) is no longer recorded as a completed, reusable
  THINK-mode experience.
• openreflex tokens disable now actually stops the local receiver instead of only rewriting Claude Code's
  telemetry settings.
• The receiver health check now verifies it is actually the OpenReflex token receiver on 127.0.0.1:4319, rather than
  treating any process on that port as one.
• The Windows UI-state lock's stale-lock reclaim can now actually trigger before a default caller times out.
• openreflex tokens --help and an unknown tokens action now print usage instead of an unhandled error, and the
  tui/memory/tokens/statusline commands are mentioned in openreflex --help.
