feat(wizard): Add User-Agent header to wizard HTTP requests#291
Conversation
Add User-Agent identification so PostHog can distinguish wizard-originated requests. Direct API calls send 'posthog/wizard' and the MCP server receives the same header so it can construct 'posthog/mcp posthog/wizard'. https://claude.ai/code/session_01UtRaBE3tQHdDxtnskKjT8K

Changes format from 'posthog/wizard' to 'posthog/wizard; version: 1.34.0' to match the convention used by other PostHog tools like the MCP server. https://claude.ai/code/session_01UtRaBE3tQHdDxtnskKjT8K
Replace the try/catch require approach with a clean import from package.json, enabled by adding resolveJsonModule to tsconfig. TypeScript handles emitting the JSON into dist/ automatically. https://claude.ai/code/session_01UtRaBE3tQHdDxtnskKjT8K
