Render the assistant's replies as Markdown (#118)
Render assistant chat output as GFM Markdown (tables, lists, code, headings), lazy-loaded so the ~150 KB renderer only ships when an assistant message shows. Hardened per review: no <img> (exfiltration-beacon guard), no raw HTML, error-boundary + stale-chunk recovery around the lazy chunk, GFM column alignment, and memoized parsing.

// In dev, Vite serves the SPA with HMR and proxies /api to the Go backend. The
// backend listens on PANSY_PORT (default 8080); read it so the proxy target
// tracks an overridden port. The production build is embedded into the Go binary
// (see internal/webdist), so no proxy is involved there.

// rides with whatever imports it, so a lazily-loaded route/feature keeps
// it out of the eager first paint. The routes are code-split via
// React.lazy (router.tsx), where the real first-paint win is.
