fix: terminal commands broken — store never initialised, hints disabled

[elasticdotventures]

Problem

Terminal commands on promptexecution.com are completely non-functional:

1. Typing any command (hello, comic, 😁) and pressing Enter produces no output — the terminal gets stuck in "executing" state
2. Command autocomplete/suggestions are disabled — users can't discover available commands
3. Console shows Error: The store must be initialized before reading on every keystroke

Root Causes (3 bugs)

1. vue-web-terminal plugin never initialised (src/main.ts)

The default export of vue-web-terminal is the component itself, not the plugin. app.use(component) silently no-ops because the component has no install() method. The library's install() — which calls initStore() — is only available via createTerminal(). Without it, every command hits getStore() → throws → the library catches it and swallows the success() callback.

2. Socket store registered unconditionally (src/main.ts)

useSocketStoreWithOut(app) was called before the env-var guard, registering a Pinia store that references websocket state even when VITE_TERMINAL_WS_URL is unset. Fixed by moving it inside the guard and calling setupStore(app) directly for Pinia.

3. Command hints disabled (src/components/TheXTerm.vue)

:enable-example-hint="false" disabled the autocomplete dropdown. Set to true.

Testing

Verified on local vite preview build:

• hello → 😁 world (zero console errors)
• comic → Win95 shell with Comic/Archive/Subscribe/CLI tabs
• help → full command table listing all 7 commands
• Typing h → autocomplete shows help + hello with descriptions; Tab selects
