fix(vite): convert manualChunks to Function for Vite 8 compatibility

[Copilot]

Vite 8 (Rolldown) dropped support for manualChunks as a plain object — it now requires a function.

Change

Convert manualChunks in vite.config.js from object to function form:

// Before (Vite 7 — object form, broken in Vite 8)
manualChunks: {
  'chart': ['chart.js', 'chartjs-plugin-annotation'],
  'd3': ['d3'],
  'papa': ['papaparse']
}

// After (Vite 8 — function form)
manualChunks(id) {
  if (id.includes('chart.js') || id.includes('chartjs-plugin-annotation')) return 'chart';
  if (id.includes('/node_modules/d3') || id.includes('/node_modules/d3-')) return 'd3';
  if (id.includes('papaparse')) return 'papa';
}

Chunk grouping behaviour is unchanged.

Root Cause Analysis

Investigated the failed workflow run #23017036455.

Root cause: The agent entered a data-gathering loop, making 6+ duplicate rounds of the same MCP queries:

• get_sync_status called 3× (should be 1×)
• get_calendar_events called 20+× (should be 2×)
• search_voteringar, get_betankanden, search_anforanden, etc. each called 6+× (should be 1× each)

This consumed the entire context window with duplicate data, and the agent never progressed to article generation or safe output.

Contributing factors:

1. No explicit anti-loop instruction in the workflow
2. Large query limits (50-100 results per query) producing massive responses
3. Agent reading full CONTENT_LABELS files (~14 languages × many keys) dumping huge tables
4. No explicit phase completion markers

Fix Applied

1. Anti-loop rules (Bump actions/upload-artifact from 4.6.2 to 6.0.0 #6, Bump github/codeql-action from 3.32.1 to 4.32.1 #7) added to NON-NEGOTIABLE RULES: each MCP tool AT MOST ONCE, forward-only phase progression
2. Reduced query limits (50→15, 100→20) to prevent context overflow
3. Time-check bash commands between every phase with hard cutoffs
4. DATA PHASE COMPLETE marker after data gathering
5. Simplified to EN/SV only (translations handled by news-translate workflow)
6. Inlined Swedish CONTENT_LABELS to prevent large file reads
7. Recompiled lock file with gh aw compile (v0.58.0)
