v0.5

Summary

v0.5 publishes the updated Session-Bound Agent Identity profile documents and
release PDFs from main at commit 923c199.

Changes

• Update the SSOT draft to the v0.5 review line and rebuild docs/SSOT.pdf
  with a cover page.
• Add docs/live-red-team-report.pdf as a release artifact with a cover page.
• Add copyright and a verification notice to the live red-team report stating
  that AI-generated draft text remains under human verification.
• Keep the report's security conclusions provisional until referenced checks are
  independently confirmed.

Testing

• GitHub Actions passed on commit 923c199: CI run 28026252616.
• GitHub Actions passed on commit 923c199: Security Red Team run
  28026253160.
• Local document checks run before release: pdflatex, pdfinfo, pdftoppm,
  visual PDF inspection, and git diff --check.

Notes

• Existing inherited CoCos tags such as v0.5.0 through v0.9.0 remain in the
  repository history, but this release follows the Agents Secure Binding release
  series v0.1, v0.3, v0.4, v0.5.
• The live red-team report is explicitly marked as under verification because
  it includes AI-generated draft text.
