fix: update @opentui/core and @opentui/solid to 0.1.88

The v1.1.3 binary had a symbol mismatch between the bundled JS code
(expecting setCursorStyle) and the native library (exporting
setCursorStyleOptions), causing blank screen on TUI startup. Pinning
both packages to 0.1.88 ensures consistent types and native symbols.
Also fixes PasteEvent API change (text -> bytes).
