fix: add npm overrides to resolve Snyk vulnerabilities

Overrides added:
  @hono/node-server: 2.0.6 → 2.0.10 (fixes moderate DoS via aborted WebSocket handshake)
  less: 4.4.2 → 4.7.0 (fixes high infinite-loop vulnerability)

Package version: 0.1.3 → 0.1.4
Vuln count: 6 (before) → 0 (after). Build verified passing.

Skipped (no safe fix available):
  image-size: vulnerable range is *, no safe version to pin
  @modelcontextprotocol/sdk: proposed fix is a cross-major downgrade (1.x → 0.x)
