v0.2.0 — Relaunch as Cal + ValueGuard

Relaunch as Cal (askcal.io) + ValueGuard.

• Repointed to the Cal API. DEFAULT_BASE_URL is now https://api.askcal.io;
  the legacy vault.homeloanexpress.ai host is retired. Users who set
  CAL_API_BASE_URL explicitly need no change.
• Rebranded the package to @askcal/mcp-server. Docs, URLs, homepage, and
  the contact address now point at askcal.io. The server-side Origin header
  is the canonical Cal origin.
• New tool cal_valuation (8 tools total): ValueGuard comparable-sales
  valuation. Pass a subject property and 4+ comps, get an indicated market
  value, floor/ceiling range, over/under-priced verdict, confidence, and the
  comps used. Backed by the Cal API valuation_report executor.
• No breaking changes to the seven existing tool schemas.

v0.1.1 — Long-lived API keys

Long-lived API keys.

• Cal API now ships an /auth/api-keys endpoint that issues opaque
  long-lived tokens (cal_live_…) usable as CAL_API_TOKEN. These do
  not expire after 8 hours like session tokens — the right choice for
  any MCP client whose config persists across days.
• README updated to recommend the API key path over the session-token
  path that 0.1.0 documented.
• CLAUDE_DESKTOP_SETUP.md updated with the API key flow + a note about
  Claude Desktop's modern DXT extension system (the legacy mcpServers
  JSON path no longer survives Claude Desktop relaunches).
• No changes to the MCP server source code itself — bearer tokens are
  opaque to the server. The version bump is purely to signal "use the
  newer install docs."
