hyperlinkUri
Resolves a primitive render-frame hyperlink id to a target URI.
UI components call this from explicit user activation paths after reading TerminalRenderCache.hyperlinkIds. The lookup is outside the paint loop and returns null when metadata is unavailable or was evicted by policy.
Return
target URI, or null if none.
Parameters
hyperlinkId
cell hyperlink id; 0 means no hyperlink.
