v1.0.12

fix release

Allow soothe-nano 1.0.0 by raising the dependency ceiling to <1.1.0.

• pyproject.toml: soothe-nano>=0.9.9,<1.1.0, bump fj-ai to 1.0.12
• release.yml: guard now verifies soothe-nano 1.0.0 is on PyPI
• uv.lock: synced

Depends on soothe-nano 1.0.0 being published on PyPI. The release workflow's guard step will fail the publish until that's available.
