Solid runtime plugin support missing from plugin/loader.ts

[YumaKakuya]

Description

The TUI plugin runtime imports @opentui/solid/runtime-plugin-support at the top of packages/opencode/src/cli/cmd/tui/plugin/runtime.ts:1, which lets Solid plugins register themselves inside a compiled binary. The plugin loader used by the server process at packages/opencode/src/plugin/loader.ts does not have the same import, so a server plugin that ships compiled .tsx components cannot find its Solid runtime when loaded from a compiled binary — the plugin silently fails to mount.

Matching the existing TUI pattern is a single-line import at the top of plugin/loader.ts:

import "@opentui/solid/runtime-plugin-support"

Steps to reproduce

1. Write a server plugin that uses Solid's TSX runtime to render components.
2. Build OpenCode as a single-file binary via ./packages/opencode/script/build.ts --single.
3. Load the plugin from that binary — the TSX component never mounts because the Solid runtime was never registered in the server process.
