fix(onboard): skip Homebrew prompt on FreeBSD

[Eruditi]

FreeBSD uses pkg/ports, not Homebrew. The onboard skills wizard should not recommend Homebrew installation on FreeBSD systems.

Closes #68893

[greptile-apps]

Greptile Summary

Adds process.platform !== "freebsd" to the existing platform guard that suppresses the Homebrew installation prompt on Windows, fixing issue #68893 where FreeBSD users were incorrectly prompted about Homebrew. The change is minimal, correct, and well-scoped to the reported problem.

Confidence Score: 5/5

Safe to merge — single-line targeted fix with no functional risk.

The only finding is a P2 style suggestion about future-proofing with an allowlist approach; it doesn't affect correctness of the current fix.

No files require special attention.

**Other non-Homebrew platforms not covered**

`openbsd`, `netbsd`, and `sunos` also don't support Homebrew natively. If this guard grows to include more platforms, consider inverting the logic to an allowlist of platforms where Homebrew is actually supported (e.g. `darwin` and `linux`) rather than a blocklist:

```
const needsBrewPrompt =
  (process.platform === "darwin" || process.platform === "linux") &&
  selectedSkills.some((skill) => skill.install.some((option) => option.kind === "brew")) &&
  !(await detectBinary("brew"));
```

This is a non-blocking suggestion — the current fix is correct for the reported issue.

How can I resolve this? If you propose a fix, please make it concise.
