fix: derive WebSocket URL from API_BASE_URL in conversation screen

[Copilot]

• Update conversation/[username].tsx to use API_BASE_URL instead of hard-coded host/protocol for WebSocket URL
  • Added API_BASE_URL import from @/services/api
  • Added getWebSocketBaseUrl helper (matching the pattern in terminal.tsx)
  • Replaced hard-coded __DEV__ ? "10.0.2.2:8080" : "devbits.ddns.net" logic with getWebSocketBaseUrl(API_BASE_URL)
• Resolve conflict with base branch by incorporating reconnection logic added in add-comments
  • Added isActive flag, reconnectAttempts, and reconnectTimeoutId state
  • Wrapped connection setup in a connect() function with exponential backoff retry (max 5 attempts)
  • Added proper cleanup in the effect return that cancels pending reconnects and closes the socket

@copilot resolve conflicts please.

Resolved in 3482dd0. The base branch (add-comments) had added reconnection logic (exponential backoff, isActive guard, cleanup) to the same WebSocket effect. I've merged both changes: the reconnection logic is now incorporated while keeping the API_BASE_URL-based URL derivation.

Looks ok merge to other pr

Pull request overview

Updates the conversation screen’s WebSocket connection to derive its base URL from the same API_BASE_URL used for HTTP API calls, avoiding hard-coded dev/prod host/protocol selection.

Changes:

• Import API_BASE_URL into the conversation screen.
• Add a getWebSocketBaseUrl helper to convert http(s) base URLs to ws(s).
• Build the conversation WebSocket URL using getWebSocketBaseUrl(API_BASE_URL) instead of hard-coded __DEV__ host/protocol logic.

getWebSocketBaseUrl is now duplicated here and in frontend/app/terminal.tsx. To avoid drift (e.g., future protocol/path handling changes), consider extracting this helper into a shared module (e.g., @/services/api or a @/utils/websocket helper) and importing it in both places.
