Fix: command cli deploy contracts (#319 )

## Summary

This PR fixes several issues with the CLI deploy-contracts command to
properly support local Anvil deployments and improves the overall
contract deployment workflow.

  ### Key fixes:
  - Add support for anvil chain in the CLI deploy contracts command
- Rename PRIVATE_KEY to DEPLOYER_PRIVATE_KEY for consistency and clarity
across the deployment flow
- Fix EigenLayer contract status display for local/anvil chains by
reading addresses from the deployments file instead of config
- Fix runShellCommandWithLogger to properly throw errors on command
failure
  - Correct totalSteps in DeployTestnet.s.sol from 2 to 4

  ### Housekeeping:
- Update .gitignore to ignore the entire broadcast/ folder
(autogenerated Foundry artifacts)
- Streamline contracts/README.md with clearer structure and deployment
instructions

DataHaven AVS Smart Contracts

Implements the Actively Validated Service (AVS) logic for DataHaven, secured by EigenLayer. These contracts manage operator registration, handle cross-chain rewards via Snowbridge, and enforce slashing with a veto period.

└── test/                             # Foundry test suites

Key Components

DataHavenServiceManager (src/DataHavenServiceManager.sol): Core contract for operator lifecycle; inherits ServiceManagerBase.
RewardsRegistry (src/middleware/RewardsRegistry.sol): Tracks validator performance and distributes rewards via Snowbridge.
VetoableSlasher (src/middleware/VetoableSlasher.sol): Handles slashing requests with a dispute resolution veto window.

Development

Requires Foundry.

# Build and Test
forge build
forge test

# Regenerate TS bindings (after contract changes)
cd ../test && bun generate:wagmi

Configuration

Deployment parameters (EigenLayer addresses, initial validators, owners) are defined in contracts/config/<network>.json.

Do not edit Config.sol or DeployParams.s.sol directly; they only load the JSON.
Ensure contracts/config/hoodi.json (or holesky.json) matches your target environment before deploying.

Deployment

Two deployment paths exist: Local (Anvil) and Testnet (Hoodi/Holesky). Both install the DataHaven AVS contracts (ServiceManager, RewardsRegistry, VetoableSlasher) and Snowbridge (BeefyClient, Gateway, Agent). They differ in EigenLayer setup:

Local (Anvil)

DeployLocal.s.sol bootstraps a full EigenLayer core deployment (DelegationManager, StrategyManager, AVSDirectory, etc.) alongside DataHaven AVS and Snowbridge.

anvil
forge script script/deploy/DeployLocal.s.sol --rpc-url anvil --broadcast

Testnet (Hoodi / Holesky)

DeployTestnet.s.sol references existing EigenLayer contracts (addresses from contracts/config/<network>.json) and only deploys DataHaven AVS + Snowbridge.

NETWORK=hoodi forge script script/deploy/DeployTestnet.s.sol \
  --rpc-url hoodi \
  --private-key $PRIVATE_KEY \
  --broadcast

Supported networks: hoodi, holesky (no mainnet config yet). Artifacts → contracts/deployments/<network>.json.

How It Works

Registration: Validators register with EigenLayer via DataHavenServiceManager.
Performance Tracking: DataHaven computes reward points and sends a Merkle root to RewardsRegistry on Ethereum via Snowbridge.
Rewards Claims: Validators claim rewards on Ethereum from RewardsRegistry using Merkle proofs.
Slashing: Misbehavior triggers VetoableSlasher (subject to veto period).

See test/README.md for full network integration tests.
