fix(ui): render only the selected terminal command

[juninhokaponne]

🔗 Linked issue

Fixes #3016

🧭 Context

The terminal rendered all package manager commands and hid the inactive ones with CSS. Since they were still in the DOM, the layout wasn't consistent when the last package manager was selected.

📚 Description

This PR changes the terminal to render only the selected package manager command.

I also moved the package manager selection logic into a shared helper to avoid repeating the same code.

A regression test was added to make sure only the selected command is rendered.

📝 Walkthrough

Summary by CodeRabbit

• Bug Fixes
  • Terminal command displays now show only the currently selected package manager’s commands.
  • Install-related command suggestions (including development, types, run, and create) are now consistent with the selected package manager.
  • Copyable installation commands now derive the selected package manager correctly, with a safe fallback when needed.
• Tests
  • Added Vitest coverage to confirm Terminal views render only the selected package manager’s command variants and content.

Walkthrough

Terminal Execute and Install now render only the currently selected package manager’s command. Shared configuration lookup is used by terminal components and install-command construction, replacing CSS-based variant visibility. Tests verify selected-manager output.

Changes

Selected package manager rendering

Layer / File(s)	Summary
Package manager config lookup and command construction app/utils/install-command.ts, app/composables/useInstallCommand.ts	Adds getPackageManagerConfig with npm fallback and uses it to construct @types command parts and the full install command.
Execute.vue single-variant rendering app/components/Terminal/Execute.vue	Resolves the selected package manager, renders one execute command, and removes CSS-based visibility handling.
Install.vue single-variant rendering app/components/Terminal/Install.vue	Renders selected-manager variants for install, development, types, run, and create commands.
Terminal component tests test/nuxt/components/Terminal.spec.ts	Verifies that TerminalExecute and TerminalInstall render only commands for the selected package manager, including expected counts and command text.
