Local backend endpoint audit (desktop sidecar)

Critical /api/* endpoints used by src/services/* were reviewed and prioritized for desktop parity:

Priority 1: News + summarization

• /api/rss-proxy (feed ingestion)
• /api/hackernews
• /api/github-trending
• /api/groq-summarize
• /api/openrouter-summarize

Priority 2: Markets + core telemetry

• /api/coingecko
• /api/polymarket
• /api/finnhub
• /api/yahoo-finance
• /api/cache-telemetry

Priority 3: Status / runtime health

• /api/service-status
• /api/local-status (new local-sidecar health endpoint)

Localization strategy

• The desktop sidecar now executes existing api/*.js handlers directly when available, avoiding reliance on Vercel edge runtime for core behavior.
• If a handler is not present or fails locally, the sidecar can optionally pass through to cloud (https://worldmonitor.app) so functionality degrades gracefully.
• ServiceStatusPanel renders local backend status in desktop mode so users can see whether local mode is active and which cloud fallback target is configured.
