Summary

Replace the rock logo at the top of the LazyCodex README with the new
Sisyphus Labs light OmO mark.

Changes

• Add the exact omo-icon-light.svg source asset.
• Point the root README at the new SVG.
• Record manual render and link-resolution QA evidence.

QA & Evidence

• What was tested: source hash equality, XML parsing, README path
  resolution, and a 512 px Quick Look render.
• Observed result: the committed SVG matches source SHA-256

  the README path resolves; the render showed the complete dark OmO cat mark
  on the light rounded-square background without clipping.
• Artifact: .omo/evidence/20260809-readme-light-logo/qa.md
• Why sufficient: this covers source integrity, markup validity, broken-link
  risk, and the actual user-visible render.

Risks & Residuals

• Documentation and image asset only. No runtime behavior changes.
