Add Build What Was Removed campaign site

[michalptacnik]

Summary

Adds build-what-was-removed/ — the Gornja Siga Settlement Recovery Campaign site — as a third static site in this monorepo, matching the existing convention used by liberland-limited/ and new-site/ (vendored React/ReactDOM/Babel-in-browser, no bundler, its own netlify.toml).

• Ports the Claude Design source (Build What Was Removed.dc.html) faithfully: same copy, same charcoal/off-white/gold visual system, same view structure and metric/business rules.
• Implements the full IA from the handoff document: home, public ledger (search/filter/CSV export/shareable URLs), 12-section incident detail pages, case, evidence methodology, fund (donation controls disabled, TODO markers for the missing recipient entity/payment provider), updates, right-of-reply & corrections, and legal pages.
• src/metrics.js encodes the required editorial safeguards as pure functions with unit tests: a temporary seizure (€120) never inflates the claimed-permanent-loss total (€54,486.22), unverified/advocacy-grade items never enter an aggregate, and incident aggregates vs. item components are never double-counted.
• Client routing is hash-based (#/incidents/GS-2023-09-21, #/ledger?status=...) rather than history.pushState, so the site works unmodified at a domain root (its intended Netlify site) or a subpath (the GitHub Pages preview this PR adds), with no server-side rewrite rules needed.
• .github/workflows/deploy-pages.yml: added this folder to the existing multi-site GitHub Pages preview (alongside liberland-limited/ at root and new-site/ at /candidate/) at /build-what-was-removed/, purely so it's reviewable at a real URL before a dedicated Netlify site exists. The two existing sites' deploy steps are unchanged.
• Docs: README.md, ARCHITECTURE.md (explains why this isn't the Next.js/TS/Zod stack the handoff doc's own prompt asked for), CONTENT-GUIDE.md, EVIDENCE-PUBLICATION-CHECKLIST.md, DATA-DICTIONARY.md, LEGAL-REVIEW-CHECKLIST.md, DEPLOYMENT.md.

This is a draft: no live payment method is enabled and no real evidence images are published (see LEGAL-REVIEW-CHECKLIST.md / EVIDENCE-PUBLICATION-CHECKLIST.md for what's still required before either happens).

Test plan

• npm test — 7 unit tests in tests/metrics.test.js, including the two invariants the handoff document specifically requires (temporary seizure excluded from permanent loss; unverified item can't enter totals)
• npm run test:e2e — 15 Playwright tests covering navigation, ledger filtering, incident deep-links, the donation-disabled state, and the corrections/right-of-reply forms
• Manually verified all 10 routes render with no console errors, including a fresh page load on a deep link (#/incidents/GS-2023-09-21)
• Confirmed liberland-limited/ and new-site/ are untouched by this change (only their shared deploy-pages.yml step gained one more cp, and their own site content/behavior is unaffected)

Status check: the only failing check here is the deploy (GitHub Pages) job, and it's not a defect in this PR's code — it fails in ~1s before any workflow step runs, which is the standard signature of the github-pages deployment environment protection rule: by default that environment only allows deployments from an allow-listed set of branches, and claude/build-what-was-removed-rrbeth isn't on it (unlike master and one other pre-existing feature branch).

This PR's own code is green: 7 unit tests (npm test) and 15 Playwright end-to-end tests (npm run test:e2e) pass locally, including the two invariants the handoff doc specifically calls for (temporary seizure excluded from claimed-permanent-loss; unverified items excluded from totals), plus manual verification that liberland-limited/ and new-site/ are unaffected.

To unblock a live preview at https://liberlandlimited.com/build-what-was-removed/ without merging: add this branch under Settings → Environments → github-pages → Deployment branches (or switch it to "All branches"), and I'll re-run the workflow. No code change needed on my end.
