v1.6.1 — fix ESM compat crash on startup

Hotfix: replace ink-use-stdout-dimensions (CJS) with inline useColumns() hook.
The package called require('ink') but Ink v5 is ESM-only with top-level await.

What's new:
- AX Platform Identity: Redefine GovOn as AX national infrastructure platform
- Terminal Resize Fix: Dynamic markdown renderer via useStdoutDimensions
- Centralized Config: 30+ hyperparameters in config/govon.yaml
- Rename draft_response → domain_adapter
- 16-Domain Adapter Roadmap
