feat: add pricing sync script and update model prices from OpenRouter (#27)

* fix: pin npm package versions in MCP integration templates

Prevent supply chain attacks by pinning exact versions instead of
using unpinned `npx -y @package` which pulls latest on every run.

23 of 25 integrations pinned. sqlite-mcp and aws skipped (packages
not found on npm registry).

* fix: use stable azure/mcp version instead of beta

* feat: add pricing sync script and update model prices from OpenRouter API

- scripts/sync-pricing.py fetches real-time pricing from OpenRouter
- Updated 64 price fields across 13 provider files
- Run periodically or in CI to keep prices current
