docs: refresh the project social preview

[btravers]

Apply the approved btravstack website social-card composition to entity: a prominent project name, short headline, project accent, and a larger version of its existing beetroot mascot.

Replaces the local 1200 × 630 preview PNG. The illustration itself is unchanged. The editable shared source is maintained in website PR #50.

Validation: rendered in Chromium after fonts and images loaded; checked at full and 600 × 315 thumbnail size; local asset verified identical to the canonical export. This PR changes only the image.

⛔ Files ignored due to path filters (1)

• docs/public/og-entity.png is excluded by !**/*.png

CodeRabbit blocks several paths by default. You can override this behavior by explicitly including those paths in the path filters. For example, including **/dist/** will override the default block on the dist directory, by removing the pattern from both the lists.
