* Fix logo rendering with responsive SVG and update README description

- Use generic sans-serif font for better cross-platform compatibility
- Add preserveAspectRatio for proper scaling across devices
- Adjust viewBox and text positioning for better layout
- Update README description: msgspec is a validation and serialization library

The logo now uses a simple sans font with proper responsive attributes,
ensuring consistent and readable rendering on all devices and screen sizes.

* Simplify logo: single line "msgspec-ext" in golden color

- Unified text in one line: "msgspec-ext"
- Use golden color (#a67c00) for all text
- Remove line break for simpler layout

Note: Text rendering still varies across devices. Consider using PNG
or icon-only approach for truly consistent rendering.

* Move assets to docs and use PNG logos for consistent rendering

- Move assets/ to docs/assets/ for better organization
- Generate high-quality PNG logos (600 DPI) using Inkscape
- Update README to reference PNG logos in new location
- Update README description: msgspec is a validation and serialization library

PNG logos ensure pixel-perfect identical rendering across all browsers,
operating systems, and devices, eliminating font-dependent variations.

* Fix merge-bot update command checkout issue

The update command was failing because the checkout action wasn't
specifying which repository to checkout from. This caused it to only
fetch the default branches and not the PR branch.

Added 'repository' parameter to the checkout action to explicitly
specify the head repository, fixing the branch checkout issue.
