Pull request overview

Fixes dropdown rendering issues in Unity Helpers’ custom drawers (notably on Linux) and cleans up Markdown documentation list formatting, while bumping the package version to 3.2.1.

Changes:

• Clamp invalid selected indices for WValueDropDown / StringInList IMGUI popups to avoid “phantom” rows.
• Harden dropdown label rendering by providing non-empty fallback labels when option labels are null/empty.
• Reformat multiple docs pages so nested lists and list/code-blocks render correctly; bump version + update changelog/templates/tests.
