docs: comprehensive documentation update - production ready at 85%

Summary:
- Complete README.md with dyadic design, examples, status, CLI reference
- Update STATE.scm: 40% → 85% completion, production-ready phase
- Document 2026-02-07 session accomplishments and metrics
- Add integration test files for affine/linear modes and e2e testing
- Binary: 2.1 MB stripped, 150+ tests passing
- Full CLI with --mode flag for affine/linear type checking

Deliverables:
- README.md: Features, quick start, examples, status table
- STATE.scm: Updated completion, phase, session history
- tests/integration_affine_mode.rs: 7 affine mode tests
- tests/integration_linear_mode.rs: 9 linear mode tests
- tests/integration_e2e.rs: 8 end-to-end compilation tests

Status: Production-ready with both affine and linear modes functional
