hypothesisctl v0.2.0

Adds a dependency-free composite GitHub Action for fail-closed experiment and AI-agent evidence gates. Inputs cross the shell boundary through quoted environment variables; local regression coverage includes paths with spaces and a shell-injection-shaped policy. The public workflow passes the Action smoke test plus Python 3.10–3.13, using immutable current official Action pins without deprecation annotations. Source commit: 1d2d8f0.
