feat: Add customizable URI template manager factory to MCP server

Implement URI template functionality for MCP resources, allowing dynamic
resource URIs with variables in the format {variableName}.

- Enable resource URIs with variable placeholders (e.g., "/api/users/{userId}")
- Automatic extraction of variable values from request URIs
- Validation of template arguments in completions
- Matching of request URIs against templates

- Add new URI template management interfaces and implementations
- Enhanced resource template listing to include templated resources
- Updated resource request handling to support template matching
- Test coverage for URI template functionality

- Adding a configurable uriTemplateManagerFactory field to both AsyncSpecification and SyncSpecification classes
- Adding builder methods to allow setting a custom URI template manager factory
- Modifying constructors to pass the URI template manager factory to the server implementation
- Updating the server implementation to use the provided factory
- Add bulk registration methods for async completions
