feat: support deno create for project initialization (#3706)

## Summary
- Add a `./create` export to `@fresh/init` so users can scaffold
projects with `deno create @fresh/init` (Deno 2.7+)
- The old `deno run -Ar jsr:@fresh/init` continues to work but now shows
a deprecation warning

**New way (Deno 2.7+):**
```sh
deno create @fresh/init
```

**Old way (still works, with warning):**
```sh
deno run -Ar jsr:@fresh/init
```
