Pass secrets through reusable workflow chain

[Copilot]

SLACK_BOT_TOKEN used in test.yml's Slack notification step was unavailable because secrets don't propagate automatically through reusable workflow calls. The chain release.yml → test-release.yml → test.yml was missing secrets: inherit at each hop.

Changes

• release.yml: Add secrets: inherit to the test-release.yml call
• test-release.yml: Add secrets: inherit to the test.yml call
