fix(native): terminal not updated on new capabilities

[AnatoleLucet]

When rendering right after creating the renderer, features that depend on special capabilities (e.g. hyperlinks) won't work right away because the capability response has not been processes/received yet.
It results in a terminal output were some features won't work until their cells are updated.

For instance:

const rdr = await createCliRenderer();

const l = new TextRenderable(rdr, {
  content: t`a link: ${link("https://google.com")(underline("Click Me!"))}`,
});
rdr.root.add(l);

If we render a simple link right after creating the renderer (on a terminal that supports OSC8), the link won't work until these cells are re-rendered by the renderer, because the initial render did not send the OSC8.

To fix it, i added a forced render after processing new capabilities to make sure every feature works correctly with the latest capabilities.

made a little update to the pr because i realized my previous fix in the zig renderer could produce half-baked renders if stdin is processed mid-draw.

this is now fixed. i moved the "re-render when receiving capabilities" logic to typescript so it can be properly scheduled with the rest.
