feat: convert smart contract workflow to prioritize Hardhat over Foundry

HARDHAT CONVERSION: Switch to CI-friendly Hardhat as primary tool

Major Changes:
✅ Prioritize Hardhat over Foundry for CI/CD
✅ Add tool field to matrix for clear separation
✅ Clean installation with npm instead of curl installers
✅ Better CI compatibility and reliability

New Matrix Structure:
- aitbc-token (Hardhat) ✅
- contracts-root-hardhat (Hardhat) ✅
- contracts-root-foundry (Foundry) - legacy support ⚠️

Hardhat Benefits:
🔥 CI-friendly and reliable
🔥 npm install instead of curl installers
🔥 No PATH issues or shell sourcing problems
🔥 Stable ecosystem with JS/TS tooling
🔥 Widely used in production

Foundry Changes:
⚠️ Marked as legacy support only
⚠️ Added migration recommendations
⚠️ Kept for backward compatibility
⚠️ Optional installation with warnings

Workflow Improvements:
1. Installation:
   - Hardhat: npm install --legacy-peer-deps ✅
   - Foundry: Optional with warnings ⚠️

2. Compilation:
   - Hardhat: npx hardhat compile ✅
   - Foundry: forge build (legacy) ⚠️

3. Testing:
   - Hardhat: npx hardhat test ✅
   - Foundry: forge test (legacy) ⚠️

4. All Steps:
   - Clear tool separation
   - Priority messaging
   - Migration suggestions
   - Better error handling

Impact:
- Much more reliable CI/CD execution
- No more Foundry installation issues
- Faster workflow execution
- Better developer experience
- Clear migration path

This converts the problematic Foundry workflow into a
reliable Hardhat-first approach while keeping Foundry
support for legacy projects that need it.
