v0.3.4 changelog

Fixed

• Fixed localized /zh/ homepage presentation so it renders as a home landing page instead of a regular documentation page.
• Fixes the GitHub Pages logo path so repository-base deployments load the site logo correctly.

Changed

• Refined /en/ and /zh/ index content around concise hero actions, feature cards, quick links, ecosystem links, and LLM entrypoints.
• Updated package version, release notes, LLM indexes, and version navigation to v0.3.4.
