Subject: [PATCH] #26 feat: add Miri testing for unsafe code validation

- Add .github/workflows/miri.yml
- Run Miri on push/PR to main + weekly on Mondays
- Use MIRIFLAGS for symbolic alignment check and isolation disable
- Validates all unsafe code for undefined behavior
- All 62 tests pass under Miri without errors

Benefits:
- Proves unsafe code correctness mathematically
- Detects undefined behavior at compile time
- Validates pointer operations and FFI safety
- Industry-standard validation for unsafe code
