fix(solid): Call lifecycle dispose on renderer.destroy

[veracioux]

Changes:

• Add onDestroy callback to CliRendererOptions
• Call solidjs dispose() in onDestroy

Addresses #288 for solidjs.

---

This is a proof of concept for fixing #288.

A potential alternative would be to add a dispose or onDestroy parameter to CliRendererConfig.

I only added it to the solidjs testSetup because I currently need it to write the opencode TUI tests. After your feedback, I can also add it to the production solidjs render and react+vue (if applicable).

That will probably conflict with #302, but should be minor.
