v1.1.0: Go packages, Maven and Gradle dependency edges

Added

• Go: a module that builds several binaries (cmd/*) is split into one project per package, linked by its own imports. A change to internal/foo selects only the binaries that import it.
• Maven: modules depend on their parent pom and on sibling artifacts. Aggregator poms (packaging pom) build nothing.
• Gradle: project(':a:b') references create dependency edges.
• Docs: a recipe for calling an existing reusable workflow once per affected project, and a guide for migrating from on.paths filters.

Fixed

• Go external test packages (package foo_test) no longer create false dependency cycles.
