Add npm package installation & usage docs to README

[Copilot]

The README was a 4-line stub with no guidance on consuming the published secure-redact npm package.

Changes

• Install — npm install secure-redact command and npm/license badges
• Quick start — import { SecureRedact } example with onComplete handler showing file download + evidence log access
• Props table — all 8 props with types, defaults, and descriptions
• Supported document types — 6 document types (Aadhaar, PAN, Health Report, ITR, Invoice, Bank Statement) with their detectable fields
• Pipeline diagram — upload → OCR → 4-layer PII detection → fusion → redacted file
• EvidenceLog interface — TypeScript type for the onComplete audit payload
• Bundler requirements — Vite recommended; Webpack 5+ supported with asset/resource note for worker syntax
• Links — direct links to https://www.npmjs.com/package/secure-redact and ARCHITECTURE.md

import { SecureRedact } from 'secure-redact';
import 'secure-redact/style.css';

<SecureRedact
  apiKey="your-gemini-api-key"
  onComplete={(maskedFile, evidence) => {
    // maskedFile: redacted File ready to download/upload
    // evidence: EvidenceLog with per-entity action audit trail
  }}
/>

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• www.npmjs.com
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node /home/REDACTED/work/_temp/ghcca-node/node/bin/node --enable-source-maps /home/REDACTED/work/_temp/copilot-developer-action-main/dist/index.js (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
