comptime/rolldown fails with "Could not find package 'vite'" in Deno + rolldown environment

Nobody has claimed this yet.

Environment
- comptime version: 0.1.0
- rolldown version: 1.0.2
- Runtime: Deno (npm compatibility layer)
- No Vite in the project

Repro

Install comptime, add the rolldown plugin to a rolldown config, and run the build:

```ts
// rolldown.config.ts
import { comptime } from 'comptime/rolldown';
import { defineConfig } from 'rolldown';

export default defineConfig({
input: 'src/main.ts',
plugins: [comptime()],
});
```

Error

```
TypeError: Could not find package 'vite' from referrer
'file:///.../.../node_modules/comptime/dist/rolldown.js'
```

Expected behaviour

comptime/rolldown should work in any rolldown environment without requiring Vite as a peer dependency. Rolldown is a standalone bundler- projects using it may not have Vite installed at all.

Actual behaviour

comptime/rolldown's entry point imports from vite internally, causing a hard failure at startup when Vite is not present.

Analysis

The dist/rolldown.js entry point appears to share code with the Vite plugin and transitively pulls in a vite import. The rolldown plugin should be self-contained and not depend on Vite's module graph. The comptime/rollup export may have the same issue.

Suggested fix

Ensure comptime/rolldown (and comptime/rollup) have no direct or transitive imports from vite. The rolldown plugin's only external dependency at runtime should be rolldown's plugin API types, which are pure TypeScript interfaces.

Start by running the Deno reproduction with rolldown.config.ts, then inspect the comptime/rolldown entry point at dist/rolldown.js and trace its imports. Done means the rolldown plugin starts in a project without Vite and the related comptime/rollup export has no direct or transitive Vite dependency.
