Add LICENSE file

[N-thnI]

Description

Add the missing LICENSE file so the repo is actually legally open source.

Problem Statement

The repository has no LICENSE file. As the org's treasury/control-plane repo, this is the same gap flagged in the other repos: without an explicit license, contributors and downstream users have no legal permission to use, modify, or redistribute the code.

Proposed Changes

• Add MIT LICENSE at repo root
• Copyright line: Copyright (c) 2026 Vero Core Engine contributors
• Link it from README

Technical Implementation Scaffolding

• Target Repository: vero-core-engine
• Target Path: root/LICENSE
• Branch Naming: chore/issue--add-license
• Authority Context: Repository hygiene / non-code

Acceptance Criteria

• LICENSE file present at repo root and recognized by GitHub's license detector
• GitHub's community-profile API reports license as non-null
• README links to it

Definition of Done

• Reviewed by lead maintainer
• Pull request merged via verified status check
