feat: test improvements

[TateB]

changes:

• switched from yarn to bun for package manager
• using typescript esm setup for hardhat (see https://github.com/NomicFoundation/hardhat/issues/3385#issuecomment-1841380253)
• test changes
  • all now in typescript
  • removed ethereum-waffle, replaced with @ensdomains/hardhat-chai-matchers-viem for fully typed test matchers
  • using deploy fixtures, instead of shared setup in beforeEach
  • refactored any tests that required the result of a prior test to run correctly, all tests are now entirely independent
  • removed usage of ethers (and in some cases web3) in favour of viem for better types
  • fixed any tests that were not running correctly, or were not testing what was expected
  • ci tests run in parallel
• deploy changes
  • using viem
  • viem.deploy function [1]
  • viem's deployContract for devnet
  • hardhat-deploy's deploy for live networks
    • for pending transaction save which can be resumed
  • using anvil for testing deploy on ci (significantly faster than hardhat, but doesn't have the same stack tracing)
  • multicall TLD setup for speed + gas efficiency
• removed unused dependencies (thanks @talentlessguy)

note [1]: using deploy from hardhat-deploy on a devnet deploy is very slow, which i think is related to ethers provider polling parameters for a receipt (it becomes apparent past the set_tlds deploy script). this is why the usage is switched over for devnet to just use viem's deployContract, but still saves the deployment into hardhat-deploy's deployment manager which allows it to easily be accessed later. live network deploys still use deploy, but speed isn't relevant for them.
