📝 Walkthrough

Walkthrough

This pull request removes the backend proxy infrastructure for Chatwoot and reconfigures the frontend to communicate directly with the external Chatwoot service. The API key is now sourced from environment variables, proxy routes and headers are eliminated, and routing logic is updated accordingly.

Changes

Cohort / File(s)	Summary
Chatwoot Widget Configuration app/[lang]/_components/ChatwootWidget.tsx	Updated Chatwoot SDK configuration to source API key from NEXT_PUBLIC_CHATWOOT_API_KEY environment variable and changed base URL from internal proxy (/api/chatwoot) to external host (https://app.chatwoot.com).
Backend Proxy Infrastructure Removal app/api/chatwoot/[...path]/route.ts	Entirely removed the Chatwoot proxy route handler containing GET and POST methods that forwarded requests, managed headers, and handled responses (135 lines deleted).
Routing Configuration Updates middleware.ts, next.config.ts	Removed Chatwoot-specific exclusions from middleware matcher and deleted proxy header configuration block and URL rewrite rules that forwarded requests to the internal proxy endpoint.

Poem

🐰 A hop and a skip, the proxy's now gone,
Direct to Chatwoot, our chat carries on!
No middleware detours, just straight to the cloud,
The config's now cleaner, we're rather quite proud!
