Original GitHub issue: https://github.com/LiveContainer/LiveContainer/issues/868

Add basic support for running userscripts inside LiveContainer using WKWebView’s WKUserScript. This would let users bring Tampermonkey/Greasemonkey scripts into iOS containers.

Proposal

Allow importing .user.js files with metadata (@match, @run-at, @grant).
Inject scripts at document-start or document-end based on metadata.
Provide a minimal Greasemonkey API shim:
- GM_getValue / GM_setValue
- GM_addStyle
- GM_xmlhttpRequest (via native bridge)

Benefits

Enables automation and UI customization currently only possible on desktop.
Makes LiveContainer far more versatile without breaking iOS sandbox rules.
