chore(brand): align category to Care Intelligence Platform + npm hygiene (#11)

Coherence sweep across Upstream-family repos surfaced:

1. README intro paragraph and footer both said "Payer intelligence
   Platform" (lowercase 'i', wrong category). Canon per
   _config/BRAND.md and _config/CONSISTENCY.md is "Care Intelligence
   Platform" — established as the category framing on 2026-05-03 and
   used by upstream-skills, upstream-community, and the org profile.
   Fixed both occurrences.

2. package.json description was generic ("MCP server for Upstream
   care intelligence"). Replaced with category-aligned, npm-shopfront
   ready copy. No em dash (forbidden in outbound copy per VOICE.md).

3. Added standard npm registry hygiene fields the published v0.2.0
   package was missing: keywords, author, license (was implicit via
   LICENSE file), homepage, repository, bugs, engines (node >=20 per
   CI), files allowlist. None of these change runtime behavior; they
   surface on npmjs.com/package/@upstream-intelligence/mcp.

4. Added npm version badge to README so release state is visible at
   a glance.

No version bump (coherence sweep, not a release). Build clean, 9/9
tests pass.

-A Model Context Protocol server that exposes Upstream's Payer intelligence Platform as a set of tools Claude can call directly.
+A Model Context Protocol server that exposes Upstream's Care Intelligence Platform as a set of tools Claude can call directly.
 
 Your billing team is in Claude already. They are asking Claude to draft appeals, decode denial codes, and explain payer behavior. With this MCP installed, Claude does not guess. Claude calls Upstream's network of operators and gets the real answer with specific dollar impact and the recommended fix.
