feat(search_modules): Add pagination limit and filter parameters to reduce API costs

[sks]

PCI review checklist

• I have documented a clear reason for, and description of, the change I am making.

Summary

This PR adds pagination and filtering parameters to the search_modules tool to reduce API costs and improve search efficiency.

Problem

Each module search was returning all matching results, leading to expensive API calls due to large response payloads.

Changes

Added the following parameters to search_modules:

Parameter	Type	Default	Description
limit	int	10 (max: 100)	Maximum number of results to return
provider	string	-	Filter to a specific provider (e.g., aws, google, azurerm)
namespace	string	-	Filter to a specific namespace
verified	bool	false	If true, only return verified partner modules

Impact

• Reduced API costs: Default limit of 10 results significantly reduces response payload size
• Targeted searches: Filters enable more precise queries, further reducing unnecessary data transfer
• Pagination support: Combined with existing current_offset, enables efficient paging through large result sets

API Reference

These parameters are supported by the Terraform Registry API.
