chore(storage): license exact-ref compatibility runners

Add the repository-standard Apache 2.0 header to the Linux runner, PowerShell forwarding entrypoint, and Python fixture while preserving each interpreter or command entry position.

Constraint: limit the follow-up to the three Task 7 files and leave their exact-ref, controller provenance, argument forwarding, migration, snapshot, and cleanup behavior unchanged

Rejected: CI-only exclusions, generated header variants, moving shebangs, changing runtime semantics, or touching the pre-existing .codex recovery state

Confidence: high

Scope-risk: comment-only headers alter controller file hashes and therefore require a fresh post-commit self-SHA matrix, but do not alter compatibility behavior

Directive: Option C Storage Task 7 CI license follow-up

Tested: SkyWalking Eyes v0.8.0 targeted header check changed from three invalid files to three valid files; Bash syntax; Python AST; Linux and PowerShell help and mixed-help exit codes; cached diff check

Not-tested: post-commit clean-tree full header scan and self-SHA exact-ref matrix, which follow this commit; shellcheck unavailable; CI workflow wiring remains unchanged
