Add options in Transport.send method (#408)

Add support for `TransportSendOptions` in `Transport.send` method

## Motivation and Context
This change extends the `Transport.send` method signature to support
advanced transport features like resumption tokens and progress
callbacks. This is needed to enable:
- Long-running request resumption after reconnection
- Request-response association tracking
- Progress token handling in transport layer

needed for #235 

## How Has This Been Tested?
All transport tests passed

## Breaking Changes
Yes, it’s necessary to update the custom Transport implementations.
For users who rely on the transports provided by the sdk, there’s no
breaking change

## Types of changes
- [x] Bug fix (non-breaking change which fixes an issue)
- [x] New feature (non-breaking change which adds functionality)
- [ ] Breaking change (fix or feature that would cause existing
functionality to change)
- [ ] Documentation update

## Checklist
- [x] I have read the [MCP
Documentation](https://modelcontextprotocol.io)
- [x] My code follows the repository's style guidelines
- [x] New and existing tests pass locally
- [x] I have added appropriate error handling
- [x] I have added or updated documentation as needed
