[codex] ship Windows Lawful Nova coding shell

[warheart1984-ctrl]

What

Packages Lawful Nova as a native Windows-first agentic coding shell in the agentic-coding-agent repo.

Includes:

• local nova Python source package with CLI, API, lawful runtime, receipts, governance primitives, and chain contract fields
• Windows bin/nova.ps1 and bin/nova.cmd shims
• productization/readiness gate with identity, trace, authority-boundary, and reproducibility checks
• bootstrap updates to create/install the local .venv
• verifier updates for repo-local Python/CLI and Docker-as-optional Windows-native posture
• smoke tests for CLI/API/chain readiness

Why

A fresh Windows checkout should have the source it needs to run the Lawful Nova coding-agent shell without committing generated .exe files, model weights, local virtualenvs, or runtime databases.

Validation

• ..\.venv\Scripts\python.exe -m pytest tests -q -> 3 passed
• ..\.venv\Scripts\python.exe scripts\nova_productization_gate.py --json-out .runtime\nova_productization_report.json -> local_lawful_slice_ready true, chain_contract ok
• powershell -ExecutionPolicy Bypass -File setup\verify.ps1 -> 21 passed, 0 failed
• git diff --check -> no whitespace errors; only line-ending warnings
• binary scan for .exe, .msi, .dll, .pyd, etc. -> no files found

Notes

No generated executable files are included. Docker remains optional for the native Windows path.
