feat: optimize contract size with dependency cleanup and aggressive compiler flags

- Removed unused libsecp256k1 and alloy-sol-types dependencies
- Applied aggressive compiler optimization flags (opt-level=z, lto=fat, strip=symbols)
- Consolidated redundant keccak256 imports
- Removed tiny-keccak feature from alloy-primitives
- Current size: 24.8 KiB compressed (25,431 bytes)
- Target: under 24KB (24,576 bytes) - need 855 bytes reduction
- All 27 unit tests passing, functionality preserved
