fix: Align semantic status check with CodexLens checkSemanticStatus

- Use checkSemanticStatus() from codex-lens.ts instead of isEmbedderAvailable()
- Returns accurate detection of fastembed installation status
- Fix install guide link to navigate to CLI Manager and open CodexLens config
- Update i18n: "Install Guide" -> "Go to Settings" (EN/ZH)
