Add: tensor trade support (#93)

# Pull Request Description
Add Tensor Trade SDK support for NFT trading operations

## Related Issue
Fixes #20

## Changes Made
This PR adds the following changes:
- Added `tensor_trade.ts` file in `src/tools` with NFT trading
functions:
  - `listNFTForSale`
  - `buyNFT`
  - `cancelListing`
- Integrated Tensor Trade functions into Langchain tools
- Added proper error handling and validation for NFT operations

## Implementation Details
- Integrated `@tensor-oss/tensorswap-sdk` for Tensor Trade Swap
- Added support for listing, buying, and canceling NFT listings
- Implemented proper transaction building and signing
- Added validation checks for NFT ownership and wallet balance
- Supports both compressed and non-compressed NFTs

## Transaction executed by agent 
Test transaction on mainnet:

## Prompt Used
I want to list my NFT for sale on Tensor Trade
NFT Mint Address: [NFT_MINT_ADDRESS]
Price: 1 SOL
Expiry Time: 3600

## Additional Notes
- Will add more comprehensive error handling based on testing results

## Checklist
- [x] I have tested these changes locally
- [ ] I have updated the documentation
- [ ] I have added transaction links
- [x] I have added the prompt used to test it
