Replace go-chi/render with go-pkgz/rest for JSON responses and custom
helpers for HTML/plain text responses.
Key changes:
- Replace render.JSON/render.Status with rest.RenderJSON and explicit
w.WriteHeader() calls
- Replace render.DecodeJSON with json.NewDecoder().Decode()
- Add SendErrorJSON helper that sets Content-Type header before
WriteHeader (required since rest.RenderJSON can't set headers after
WriteHeader is called)
- Add HTMLResponse and PlainTextResponse helpers
Fix export double-execution in migrator.go:
The original code called Export twice - once to io.Discard to check for
errors, then again to actually write. This was wasteful and had a race
condition risk. Now file mode buffers to memory first for atomic
success/failure, while stream mode writes directly with proper error
handling.
