Add standalone policy/governance files to match the TypeScript SDK's
structure (PR #1547). These files are checked by the tier-check CLI.

- VERSIONING.md: semver policy adapted for Python (compatible-release
  specifiers, DeprecationWarning, Python version support)
- ROADMAP.md: spec tracking and v2 milestones (shared across SDKs)
- DEPENDENCY_POLICY.md: extracted from CONTRIBUTING.md and expanded
  with policy rationale (update triggers, automated tooling, pinning)
- CONTRIBUTING.md: updated to reference standalone DEPENDENCY_POLICY.md
