v0.3.0 - remove legacy dependency files

v0.3.0

Second-phase dependency-management cleanup release.

• Removes legacy root requirements.txt and constraints.txt dependency entry points.
• Installs the local platform project with uv sync --frozen in CI, Docker, and Cloud Run environment sync.
• Keeps pyproject.toml and uv.lock as the dependency source of truth.
• Adds package discovery for the existing flat-layout modules where needed.
• Keeps the static review gate blocking unexpected file deletions while allowing the intentional removal of legacy dependency manifests.

v0.2.0 - py dependency management

v0.2.0

Dependency-management release for the platform runtime.

• Uses pyproject.toml and uv.lock as the locked dependency source for CI, Docker, and Cloud Run environment sync.
• Keeps legacy requirements.txt / constraints.txt for compatibility during the staged migration.
• Keeps --no-install-project until package layout cleanup is handled separately.
• Version metadata is bumped to 0.2.0.
