ci: use the shared tools copyright hook

[AlexanderLanin]

Why

Use the copyright checker from eclipse-score/tools for both local pre-commit checks and CI, replacing the repository’s Bazel-based check.

• Add the copyright pre-commit hook pinned to v0.0.2 and run it against all files in CI.
• Remove the obsolete Bazel copyright target and its README command.
• Retain score_tooling because lint aspects, unit-test macros, and the Dash license checker still depend on it.

Closes #28
