v0.3.2-beta.2

Pre-release for 0.3.2.

Fixes

• Make frontend a soft dependency (after_dependencies) instead of a hard dependencies entry. The hard dependency forced frontend setup during config-flow loading, which broke the test suite (no hass_frontend module in CI). Setup ordering before add_extra_js_url() is still guaranteed in real installs.
• Sort manifest keys to satisfy hassfest validation.

Supersedes v0.3.2-beta.1 (which contained the failing test build).
