Update core project documentation to reflect recent architectural changes,
security implementations, and deployment requirements. This includes
refining the status tracking system and cleaning up the repository.
- Update `AGENT.md` and `STATUS.md` to establish `AGENT.md` as the primary
source of truth for project state and contracts.
- Add `CLIENT_DELIVERY.md` as the definitive checklist for customer
delivery status.
- Update `DEPLOYMENT.md` with new production domain information,
storage linking instructions, and secure disk configuration for
commitment forms.
- Update `README.md` with current migration/model counts and link to
the new delivery checklist.
- Update `.gitignore` to exclude local AI tools and Postman workspaces.
- Remove obsolete `IFNEX-Logistics.zip` and `IFNEX_DEPRECATED_FILES_NOTICE.md`.
- Fix typos in `DEPLOYMENT.md` deployment scripts.
