fix: 修正審查員 P7-P8 問題

P7: envInputs 從 .paperclip.yaml 頂層移至 projects.daily-quant-pipeline.inputs.env
    讓 importer 能正確讀取 env input 並進 manifest
    同步補入 ALPACA_API_KEY / FMP_API_KEY 需求聲明

P8: .mcp.json 補齊 alpaca 與 fmp MCP server
    docs/agent-skill-mapping.md 新增 Runtime 狀態說明表（active / needs-key / local-runtime）
    docs/mcp-plan.md 狀態從「規劃中」改為「已配置」，補 Alpaca/FMP 安裝說明
