docs: clarify extension system status and remove stale examples (#862)

[noor202401938-netizen]

Description

Following the core architecture cleanup in #844, this PR synchronizes CONTRIBUTING.md and EXTENSIONS.md with the current codebase:

• Adds a status alert banner to EXTENSIONS.md clarifying that runtime extension loading, render hooks, and marketplace access are disabled in 1.3.5+.
• Removes references to the non-existent extension-examples/ directory.
• Updates CONTRIBUTING.md to point contributors toward active priorities (export optimizations, platform recording reliability, wallpapers, and translations) rather than paused extension APIs.
• Directs wallpaper and cursor contributors to built-in assets (src/lib/wallpapers.ts and src/assets/cursors/).

Motivation

Resolves #862. The documentation previously pointed contributors to deleted extension APIs and a missing extension-examples/ directory, causing confusion for new contributors.
