feat(web): render terminals with libghostty-vt - #4860

💭 Looking at this PR for the Ghostty web terminal, I'm checking whether any Effect service conventions apply to the new TypeScript code. The changes span the desktop app, web components, and terminal modules, but none of them appear to be creating Effect services—it's mostly plain TypeScript classes. I don't see any Effect imports in the new files either, so the standard Effect patterns don't seem relevant here. I'm checking the scope of changes and confirming there are no violations of Effect service conventions, though I'm noticing a conflict between the instruction to output "All clear" as plain text versus the requirement for a JSON schema response.
