## Pull Request: Sovereign Forge

### Description

Clearly describe the changes you're proposing. What problem does this solve? What new capability does it add?

### Type of Change

- [ ] Bug fix (non-breaking change that fixes an issue)
- [ ] Feature (new capability, non-breaking change)
- [ ] Breaking change (significant alteration to API or behavior)
- [ ] Documentation (README, guides, comments)
- [ ] Refactoring (code cleanup, no functional change)
- [ ] Performance (optimization, benchmarking)
- [ ] Security (vulnerability fix, hardening)

### Testing

Link to test results and describe testing performed:

- [ ] Unit tests added/updated: `make -f netlister/Makefile.sov test-all`
- [ ] Conformance tests pass: Phase 1-5 all 77+ tests passing
- [ ] ASan/UBSan clean: No memory errors detected
- [ ] Fuzzing: 1M+ libFuzzer iterations without crash
- [ ] Manual testing: Describe steps taken

### Security Impact

Does this change touch:

- [ ] Cryptographic code (Blake3, Ed25519)
- [ ] Memory management (allocation, pointers)
- [ ] Certificate generation or verification
- [ ] Key material or signatures
- [ ] Input validation or preconditions

**If yes:** Describe security implications and mitigations.

### Performance Impact

- [ ] No performance change
- [ ] Performance improved (describe: 2x faster for N×N matrices)
- [ ] Performance regressed (describe: now O(N^4) instead of O(N^3))

Provide benchmark results if applicable:

```
Before: matrix_invert 100×100 = 50ms
After:  matrix_invert 100×100 = 45ms (10% improvement)
```

### Breaking Changes

Does this change break existing APIs or proof certificates?

- [ ] No breaking changes
- [ ] Yes, breaking change (version bump required, migration path needed)

If breaking: describe migration path for users.

### Documentation

- [ ] README updated (if user-facing feature)
- [ ] DEVELOPER.md updated (if developer-facing)
- [ ] ARCHITECTURE.md updated (if architectural change)
- [ ] Code comments added (if complex logic)
- [ ] Formal proof updated (if algorithm changed)

### Checklist
