Darkwood video generator

Symfony CLI tool that turns a YAML video definition into per-scene assets (voice, video), persists run state, and produces a render manifest.

Operational guide (environment variables, Replicate setup, benchmark mode, where files land): see docs/mvp-video.md.

composer install
php bin/console app:video:generate examples/video.yaml

Run tests (no live Replicate calls; HTTP is mocked in provider tests):

make phpunit
# or: ./bin/phpunit (delegates to tools/phpunit)
