### Summary
This PR build upon #145 to also adds filtering by resource type to
`list_network_requests` (Also see: #137 and #107).
### Motivation
Agents often need specific request types (e.g., scripts, stylesheets,
images). Filtering reduces noise and improves performance.
### Changes
- **New parameter**: `resourceType` (array) to filter by resource types
- **Supported types**: all resource types supported by Puppeteer
- **Backward compatible**: when omitted, returns all requests
Filtering runs before pagination, so pagination applies to the filtered
results.
