Elie Habib 2268df2bfc feat(mcp): add MCP data panel for user-connected servers (#1835)
* feat(cii): add displacement signal and extend ACLED window for post-conflict accuracy

ACLED's 7-day window scores post-ceasefire countries (e.g. Lebanon) near
zero despite ongoing destruction, because battle events dried up after the
November 2024 ceasefire. Two fixes:

1. Displacement signal (UNHCR): reads displacement:summary:v1:YEAR from
   Redis and maps ISO3→ISO2 codes. Log-scaled boost (max +20pts) means
   Lebanon (~1.2M displaced) gets ~12pts, Syria (~7M) gets ~18pts, and
   peaceful countries get 0. This signal persists long after a ceasefire
   because UNHCR data updates annually, not per-battle.

2. ACLED 30-day window with time decay: extends from 7 to 30 days.
   Events 0-7 days old: weight 1.0 | Events 8-30 days old: weight 0.4.
   Captures conflict tail without over-weighting stale events.

Together these make CII reflect structural reality (displaced populations,
reconstruction crisis) rather than just last-week's ACLED event count.

* fix(cii): add displacedByIso3 to emptyAux fallback

* fix(cii): rescale displacement boost and paginate 30-day ACLED query

P1: The previous formula Math.log10(n)*4 capped at 100K displaced
(log10(100000)=5, 5*4=20), making 100K and 10M identical. Rescaled
to (log10(n)-5)*8+4 anchored at the 100K threshold:
  100K→+4 | 500K→+10 | 1M→+12 | 5M→+18 | 10M→+20, floor 0.

P2: A single 30-day fetch with limit:1500 silently drops tail events
once the global count exceeds the cap, which cuts post-conflict
countries (low recent, higher older activity) exactly when they need
the signal most. Split into two independent cached queries:
  - days 0-7:  limit 1000 (full weight, same as before)
  - days 8-30: limit 1000 (0.4 weight, separate Redis cache key)
Each window gets its own event budget; no shared-function changes.

* feat(mcp): add MCP data panel to let users connect any MCP server

Users can now connect an MCP server directly from the dashboard via a new
"Connect MCP" block alongside "Create with AI". The modal fetches available
tools from the server, lets the user pick a tool + configure args + refresh
interval, then renders a live auto-refreshing panel.

- api/mcp-proxy.js: Vercel edge proxy implementing MCP streamable-HTTP
  protocol (initialize + tools/list / tools/call, SSE + JSON responses)
- src/services/mcp-store.ts: localStorage CRUD for McpPanelSpec configs
- src/components/McpConnectModal.ts: connection wizard (URL, auth header,
  tool selection, args, title, refresh interval)
- src/components/McpDataPanel.ts: auto-refreshing panel with configure (⚙)
  and refresh-now (↻) buttons; renders text or formatted JSON from tool result
- panel-layout.ts: loads persisted MCP panels on boot, adds "Connect MCP"
  block, addMcpPanel() integration
- event-handlers.ts: handles mcp- panel close (confirm + delete) and
  wm:mcp-configure event for re-opening the modal
- CSS: mcp-connect-modal, mcp-data-panel, shared btn/btn-primary/etc classes
- i18n: mcp.* keys in en.json
- tests: mcp-proxy.js added to ALLOWED_LEGACY_ENDPOINTS allowlist

* fix(mcp): add common.cancel i18n key used by McpConnectModal

* feat(mcp): add Quick Connect presets for Brave, Exa, Tavily, Context7, Web Fetch

* fix(mcp): replace search-heavy presets with diverse tool presets (GitHub, Slack, Radar, Maps, Postgres, Fetch)

* feat(mcp): add 10 quick-connect presets

Add Linear, Sentry, Datadog, Stripe, Overpass (OSM), Perplexity,
Polygon.io, Notion, Airtable, and Shodan to MCP_PRESETS, bringing
the total to 16 diverse integrations. Make preset list scrollable
(max-height 260px) to accommodate the longer list.

* fix(mcp): SSRF protection, CRLF sanitization, auth hint styling

- Block private IP ranges (RFC1918, link-local, cloud metadata 169.254.x.x)
  in mcp-proxy validateServerUrl; remove dead localhost-allow logic
- Strip CRLF from forwarded header keys/values to prevent header injection
- Use mcp-status-info class (amber) for auth notes instead of mcp-status-loading
- Simplify redundant JSON.parse guard in preset click handler

* fix(mcp): correct protocol version and send notifications/initialized

- Bump MCP_PROTOCOL_VERSION from 2024-11-05 to 2025-03-26: the current
  transport (direct POST, JSON or SSE response) is Streamable HTTP
  defined in the 2025-03-26 revision. The 2024-11-05 HTTP transport
  requires opening an SSE endpoint first to discover the JSON-RPC URL,
  which this proxy does not do. Advertising the wrong version caused
  compliant 2024-11-05 servers to fail during connection.

- Add sendInitialized() helper that fires notifications/initialized
  after a successful initialize handshake. MCP lifecycle requires this
  notification before any tool traffic; servers that enforce it would
  reject every tools/list or tools/call from this proxy. Called in
  both mcpListTools() and mcpCallTool(). Response is awaited but
  treated as fire-and-forget so non-compliant servers do not break.
