Refresh Current state for v0.1.0:82; document render-smoke build gate

Record the v82 vendor+SRI + render-smoke work in durable docs: packaging guide
gains the verified-build gate + re-vendor instructions; Current state rewritten
and compressed for v82; ROADMAP logs the deferred pre-compile-JSX alternative.

 **Keep the Contacts table — as the read-only per-person directory it already is.** Confirmed 2026-06-16: the grid models **investor entity → many people** correctly today. The grid "contacts" column is a multi-pill editor; each pill syncs to a `fundraising_contacts` row AND its own classic `contacts` row (5-person family office → 1 investor + 5 contacts, linked via `fundraising_contacts.contact_id`, migration 0004). The Contacts page is **read-only for creation** (header: "added from the Fundraising Grid"; no New-Contact button), edit-only via the detail slide-over — the desired flow already holds. Email capture already rolls **multiple people up to one investor** (matcher indexes each pill's email separately, all → same `fundraising_investor_id`; `email_investor_links` records both investor and specific person). No build here — future email-surfacing UI should present comms grouped by investor across all its people.
 
+### Front-end: pre-compile JSX, drop runtime Babel (optional, larger)
+*Logged 2026-06-16 during the v0.1.0:82 vendor+SRI work. The scoped fix shipped: React/ReactDOM/Babel are now vendored + SRI-pinned and served same-origin, and a jsdom render smoke check gates every build (`docs/guides/packaging.md`). This is the bigger alternative we deliberately deferred.*
+
+Today the app ships `@babel/standalone` (~3 MB) and transforms ~5k lines of inline JSX **in the browser on every page load**. A build step that pre-compiles the JSX to plain JS would (a) eliminate the runtime-transform blank-screen class entirely (no Babel in production), and (b) load much faster. **Cost:** it introduces a build step, which contradicts the current **"No build step"** convention (single `frontend/index.html`, inline-Babel React) — so this is a real architecture change, not a tweak. Weigh only if page-load size/latency or render robustness becomes a felt problem; the render-smoke gate already de-risks the status quo. If taken: keep the source `index.html` editable, emit a compiled artifact into the s9pk, and keep the smoke check pointed at the built output.
