docs: add contextual Dash artwork for the DevTools pipeline

[coisa]

Related Issue

Maintainer-requested contextual Dash artwork update.

Motivation / Context

Show Dash coordinating tests, refactoring and documentation at the DevTools workstation.

Changes

• Refresh docs/_static/mascot-banner.png and display its relative path from the README at width 840.
• Exclude /docs/ and root /README*.md files from package archives together.
• Add the matching Unreleased changelog entry (docs: add contextual Dash artwork for the DevTools pipeline #360).

Verification

• PNG structure, dimensions and SHA-256 verified; cleanup preserves the image bytes.
• git archive contains no docs or root README Markdown; git diff --check passed.
• composer dev-tools: cannot locate Composer autoload/dependencies in this isolated checkout.

Documentation / Generated Output

• README updated; Sphinx already references the same local banner.
• Existing wiki pointer update retained.

Changelog

• Unreleased / Changed describes the contextual banner.

Reviewer Notes

No runtime PHP code changed.

📝 Summary

Summary by CodeRabbit

• Documentation
  • Updated the README banner to display Dash at its DevTools workstation and load the image from a pinned GitHub URL.
  • Added details on the banner’s source, authorization scope, and licensing, plus records of its generation and review.
  • Updated the Unreleased changelog with the documentation and artwork changes.
• Chores
  • Brand assets are excluded from exported archives.

Walkthrough

The README banner now uses a pinned GitHub URL for the Dash image and updated alt text. Asset documentation and a generation receipt record the image’s provenance, authorization, and usage limits. .gitattributes excludes assets/brand/ from exported archives. The changelog records the refresh, and the .github/wiki submodule reference changes.

_{A rabbit sees Dash upon the page,
A pinned image marks the change.
The asset notes its source and bounds,
While archive rules keep it out.
The wiki points to commits anew,
And carrots hop in review too.}
