Review complete. This PR only bumps the platform runners Helm chart default from 0.5.9 to 0.5.10, matching the linked runners release for agynio/runners#60.

I verified:

• The linked runners issue and release context.
• Tag v0.5.10 points at merged runners commit 76be9bd.
• Terraform formatting and validation pass locally for stacks/platform.
• PR checks are green.

No changes requested.
