Add <ufo-intel-widget> embeddable UAP intelligence Web Component

[Copilot]

Transform the minimalist UFO-release dashboard concept into a plug-and-play, fully client-side Web Component — live feed, deep analytics, and a BYO-key agentic assistant — that any analyst can drop into an intranet portal with zero backend.

Lives at services/web-dashboard/public/widget/ and ships through the existing Pages workflow to https://dascient.github.io/UACP/widget/.

Changes

• ufo-intel-widget.js — single-file ES module, ~1 600 LOC, no runtime deps. Shadow-DOM style isolation; observed attributes data-source, refresh-interval, theme, llm-provider, llm-model, api-key.
• Live feed — JSON / RSS / Atom sources merged with analyst notes (IndexedDB-backed) and system alerts (new-tranche detection, source-down). Filterable, drill-in modal, clickable into the assistant.
• Deep analytics tabs — hand-rolled SVG timeline (lane per agency), force-relaxed agency × keyword network graph, file-type composition bars, ISO-8601 weekly release cadence. All filter- and refresh-aware; no Chart.js / D3 dependency.
• Agentic assistant — slide-out panel; OpenAI (SSE streaming), Anthropic, or any OpenAI-compatible local endpoint (Ollama / LM Studio / llama.cpp). Multi-turn with source citations. Slash commands /summarize /compare /report /risk /timeline /find. Client-side TF-IDF RAG keeps retrieval in-browser; only top-K snippets are sent to the LLM. Graceful credentials prompt when no key.
• Resilience & hygiene — IndexedDB dataset cache + stale banner with last-fetch timestamp. Local-only audit log of fetches, queries, user actions. CSV/JSON dataset export + Markdown chat transcript export.
• Security — API key kept only in localStorage (XOR + base64 obfuscation via TextEncoder/TextDecoder); ASCII-control-character strip before injection into Authorization / x-api-key headers; no telemetry, no external CDN, all output HTML-escaped.
• Accessibility — ARIA roles/labels, prefers-reduced-motion, keyboard shortcuts (R refresh, / open assistant, Esc close modal), focusable feed items.
• index.html demo — usage docs, configurable source/refresh controls, bundled offline sample fixture (ODNI, AARO, USN public releases) so the widget exercises every code path without network access.
• README.md — embed snippet, attribute table, privacy notes, schema documentation.

Usage

<script type="module"
        src="https://dascient.github.io/UACP/widget/ufo-intel-widget.js"></script>

<ufo-intel-widget
  data-source="https://your-mirror.example/ufo/index.json"
  refresh-interval="30000"
  theme="dark"
  llm-provider="openai"
  llm-model="gpt-4o-mini"></ufo-intel-widget>

Schema

Loader normalises any of { pdfs, images, videos }, { items }, a top-level array, or RSS/Atom into:

{ id, title, agency, url, blurb, releaseDate, type }

Deployment

No workflow change needed — static_deploy.yml already copies services/web-dashboard/public/ through the Next.js export into the Pages root.
