feat: add EIP-7594 (PeerDAS) blob support

Implements EIP-7594 blob transaction support alongside existing EIP-4844 blobs.

BREAKING CHANGES:
- `blobsToProofs` now returns `Hex[][]` or `ByteArray[][]` instead of flat arrays
  - EIP-4844: Returns `[[proof]]` (one proof per blob, wrapped in array)
  - EIP-7594: Returns `[[proof1, ...proof128], ...]` (128 cell proofs per blob)
- `BlobSidecar.proof` type now accepts `type | type[]` to support both formats

Features:
- Add optional `blobVersion` parameter ('4844' | '7594') to blob-related methods
- Automatic blob version detection based on chain ID (Sepolia uses EIP-7594)
- Add `getBlobVersion` helper for chain-based version selection
- Support for `computeCellsAndKzgProofs` in KZG interface
- EIP-7594 uses wrapper version byte `0x01` in transaction serialization
- Transaction parsing handles both 4-element (EIP-4844) and 5-element (EIP-7594) wrappers

Implementation:
- `blobsToProofs`: Returns array of proof arrays, uses `computeCellsAndKzgProofs` for EIP-7594
- `toBlobSidecars`: Handles proof arrays, unwraps single proofs for EIP-4844
- `serializeTransaction`: Flattens proof arrays, adds version byte for EIP-7594
- `parseTransaction`: Groups proofs by blob dynamically based on count
- `getBlobVersion`: Auto-detects version from chain ID with override support

Documentation:
- Update blob transaction guide with EIP-7594 information
- Add `blobVersion` parameter docs to `blobsToProofs` and `toBlobSidecars`
- Document proof structure differences between EIP-4844 and EIP-7594

Tests:
- Add comprehensive EIP-7594 test coverage (128 tests passing)
- Mock KZG implementation with `computeCellsAndKzgProofs` for testing
- Test serialization, parsing, and round-trip for both blob versions
- Verify automatic chain-based version detection

Dependencies:
- Update `@paulmillr/trusted-setups` to 0.3.0 (PeerDAS support)
- Update `micro-eth-signer` to 0.17.3 (includes `computeCellsAndProofs`)

 Blob Transactions are a new type of transaction in Ethereum (introduced in [EIP-4844](https://eips.ethereum.org/EIPS/eip-4844)) that allows you to broadcast BLObs (Binary Large Objects) to the Ethereum network. Blob Transactions are like any other transaction, but with the added ability to carry a payload of Blobs. Blobs are extremely larger than regular calldata (~128kB), however unlike regular calldata, they are not accessible on the EVM. The EVM can only view the commitments of the blobs. Blobs are also transient, and only last for 4096 epochs (approx. 18 days).

+Viem also supports [EIP-7594](https://eips.ethereum.org/EIPS/eip-7594) (PeerDAS) blobs, which use a different proof format. On Sepolia, EIP-7594 is automatically used, while other chains default to EIP-4844.
