feat: add benchmarks, unit tests, E2E and aspect tests for absolute-zero
- benches/cno_benchmarks.rs: criterion benchmarks for CNO detection, state snapshot, stack ops, hashing (5 groups, 20+ parameterized) - tests/unit/cno_properties_test.rs: 11 unit tests for CNO invariants (empty program, balanced ops, wrapping, composition, parallel, non-CNO) - tests/e2e/proof_verification_e2e.sh: full pipeline (Rust build, Coq, Lean, Z3, Agda, Zig FFI, panic-attack assail) - tests/aspect/cross_cutting_test.sh: SPDX headers, forbidden patterns, docs completeness, proof inventory, build infra, CI/CD checks - Cargo.toml: add workspace, criterion dev-dep, bench profile Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
