[Methodology] Add Statskontoret enrichment layer (agency-capacity ground truth)

[pethers]

📋 Issue Type

Feature / Methodology Hardening

🎯 Objective

Add a Statskontoret-sourced "agency capacity" evidence layer beneath document-level analysis, so implementation-feasibility claims (Kriminalvården, Polismyndigheten, Försäkringskassan) cite empirical capacity studies instead of inference.

📊 Current State (evidence from 2026-04-26 reflections)

• propositions/methodology-reflection.md Improvement 3: "Add Statskontoret enrichment for HD03252 — search https://www.statskontoret.se/ for reports on agency capacity in criminal justice benefit administration to strengthen implementation-feasibility analysis."
• week-ahead/methodology-reflection.md Improvement 4: "HD01CU25 (prison construction) involves … Kriminalvården. A Statskontoret agency capacity analysis of Kriminalvårdens implementation ability would strengthen the implementation-feasibility assessment."
• month-ahead/methodology-reflection.md Improvement 3: same theme on HD01JuU31 police efficiency.
• evening-analysis/methodology-reflection.md: R-03 (Statskontoret 2020) flagged as dated [C3].

🚀 Desired State

1. New scripts/fetch-statskontoret.ts performs targeted web_fetch against statskontoret.se search/RSS.
2. Maintain data/statskontoret/index.json (title, year, agency, summary, URL, Admiralty grade).
3. implementation-feasibility.md template auto-includes a Statskontoret evidence row for each named agency.
4. Cache TTL 30 days (Statskontoret reports are slow-moving).

🔧 Implementation Approach

1. Add www.statskontoret.se to workflow network.allowed list.
2. Skill myndigheter-monitoring extended with Statskontoret indexing.
3. Vitest test asserts every implementation-feasibility.md references at least one Statskontoret entry when an agency is named.

🤖 Recommended Agent

intelligence-operative — political/agency-capacity analysis ownership; data-pipeline-specialist consulted for fetch script.

✅ Acceptance Criteria

• Network allow-list updated in all news-*.md workflows
• scripts/fetch-statskontoret.ts with caching
• implementation-feasibility.md template auto-injects evidence row
• Vitest contract test
• Skill myndigheter-monitoring updated
