Request patch 0.1.1 deterministic Python wheel approval

[docushell-dev]

Summary

• Record the deterministic Python wheel approval request for ethos-pdf==0.1.1.
• Bind the request to source commit d3e3953b99fbc74669f82ee56b753de7db6e63e4, tree 8920cbc9bc6ae05ec0c417533513637eda12658d, build input SOURCE_DATE_EPOCH=0, and wheel SHA256 e0292276e711e75d4f7e1bb8c2c6137c6e89d4c343dd308943eb9b22094ea451.
• Add a release-candidate-prep guard so the deterministic request stays indexed, source-bound, and upload-blocked.

Boundary

• No PyPI upload is approved or performed.
• No public installation wording is approved.
• Hosted surfaces, production positioning, Windows packaged artifacts, bundled project-maintained PDFium, public benchmark reports or claims, ethos-doc, and ethos-rag remain blocked.
