Add Li.fi plugin

[sunosuporno]

Background

This PR introduces a new LiFi bridge plugin that enables cross-chain token transfers within our application. LiFi is a bridge aggregator that finds the best routes for transferring tokens across different blockchain networks, making it easier and more efficient for users to bridge their assets.

What does this PR do?

• Implements a new LifiService plugin with two main tools:
  1. lifi_get_quote: Fetches quotes for cross-chain transfers using the LiFi API
  2. lifi_bridge: Executes the bridge transaction, including automatic token approvals
• Features:
  • Supports multiple EVM chains through chain mapping
  • Handles token approvals automatically before bridging
  • Includes error handling for cases when no bridge routes are available
  • Optional API key support for enhanced rate limits
  • Comprehensive logging for better debugging and user feedback

Testing

Method	Prompt	Screenshot	Transaction Link
Getting Quotes	can you give quotes for swapping 1 USDC from Mode to Base?		NA
Bridging funds	bridge 1 USDC from Mode to Base		Transaction Link

Docs

My changes do not require a change to the project documentation.

Checklist

• I have tested this change and added the relevant screenshots to the PR description
• I updated the README if necessary to include the new plugin, wallet, chain, etc.

@sunosuporno could you rebase from main and remove the changes to the main README?

Also, could you add a README for the new plugin? 🙏

[sunosuporno]

@0xaguspunk made the readme related changes! What do you mean by rebasing? I already merged all changes in main to this branch? Am I missing something?

[0xaguspunk]

you pushed a bunch of changes to the main README in the root. I dont think these are related to the PR

[sunosuporno]

Ohh I removed it now in the latest commit ad6228c. I added as the last item in the checklist of the PR wanted it 😅

[0xaguspunk]

its failing to build, you need to delete the pnpm lock file and run pnpm install again

[sunosuporno]

Done! @0xaguspunk

[0xaguspunk]

@sunosuporno you pushed the changes of root project README, could you revert those? not needed for this PR :)
