fix: resolve Foundry installation issues in smart contract tests

FOUNDRY INSTALLATION FIX: Resolve PATH and installation problems

Issues Fixed:
❌ forge: command not found after foundryup installation
❌ PATH not properly set in CI environment
❌ Shell environment not sourced correctly

Solution Applied:
✅ Enhanced foundryup installation with fallback method
✅ Explicit PATH setup in all Foundry steps
✅ Shell environment sourcing (.bashrc/.zshrc)
✅ Alternative direct installation method
✅ PATH persistence across all workflow steps

Changes Made:
1. Installation Step:
   - Added shell sourcing after foundryup
   - Added PATH to ~/.bashrc for persistence
   - Added fallback direct installation method
   - Enhanced verification logic

2. All Foundry Steps:
   - Added explicit PATH export
   - Added shell sourcing
   - Ensured forge/cast availability

3. Error Handling:
   - Better error messages
   - Fallback installation methods
   - Graceful failure handling

Impact:
- Foundry tools now install correctly in CI
- All smart contract tests can run properly
- Gas optimization and security analysis work
- Contract compilation and testing functional

This resolves the critical issue where Foundry tools
were not available after installation in the CI environment.
