evidence: source inventory for pm25-monitoring-south-asia + problem pack index (#50)

* evidence: source inventory for pm25-monitoring-south-asia + problem pack index

Two contributions in one PR:

1. PM2.5 source inventory (task: source-inventory, literature-scout)
   - Added 3 evidence records: OpenAQ, WorldPop, Copernicus Sentinel-5P
   - Updated datasets.md with classification table (6 sources: 5 usable,
     1 limited, 1 rejected low-cost sensors)
   - Updated evidence.md with notes for all 6 records
   - Created claims.json with dry-lab-verified claim about monitoring
     gap severity and satellite uncertainty in South Asia
   - Done condition satisfied: 7 sources classified (requirement was 5)

2. Problem pack index generator
   - New script: scripts/generate-index.mjs
   - Generates docs/wiki/Index.md with a summary table and full pack
     listing showing status, domain, region, safety, progress (evidence
     count, task count, claims), and priority (needs evidence, ready,
     has claims, accepted work, needs triage)
   - Includes a 'Needs Evidence' section listing packs with <3 evidence
     records that have scoped tasks -- the highest-leverage entry points
   - Added to pnpm build pipeline and validate freshness check
   - Auto-generated; do not edit directly

All gates pass: pnpm validate, pnpm reproducibility:check, pnpm build.

* fix: allowlist Copernicus journal URLs (ACP, ESSD) for CI connection failures

Both acp.copernicus.org and essd.copernicus.org are live in browser
(200) but fail with connection errors from CI runners. Same pattern
as existing CPCB and ICIMOD allowlist entries. Connection-level
failures only; definite HTTP errors would still fail.

* fix: allowlist UNESCO IOC URL (connection timeout from CI, live in browser)

Same pattern as CPCB, ICIMOD, and Copernicus journal entries.
Connection-level failure only; definite HTTP errors would still fail.
