v0.1.0 - Workspace & CI

First tagged milestone: the project skeleton and its safety nets. No user-facing features yet -- hightower only prints a placeholder.

Included

• Hexagonal Cargo workspace: core (pure domain, zero OS deps), adapters (Windows), cli (hightower binary).
• CI: test-core (windows + ubuntu), build-cli, fmt, clippy (-D warnings), cargo-audit.
• CodeQL (Rust), Dependabot, issue/PR templates.
• Bilingual README, Code of Conduct 2.1, CONTRIBUTING, SECURITY, FUNDING.
• main protected by a ruleset (PR + 1 review + green checks; admin bypass for the maintainer).
