Describe the configured runner and fallback in both comments.

The CI runner documentation says manaflow-ai jobs do not use GitHub-hosted runners. It lists blacksmith-6vcpu-macos-15 as both the intended runner and fallback for MACOS_RUNNER_BACKGROUND. The current comments misstate where these lanes run.

Review comment at @.github/workflows/build-ghosttykit.yml at line 21:
Update the background-lane and post-merge publication comments near the
`runs-on` expression to describe the configured runner accurately: in
`manaflow-ai`, use `MACOS_RUNNER_BACKGROUND` with `blacksmith-6vcpu-macos-15` as
the fallback, and do not describe these jobs as using free GitHub-hosted
capacity.

Update the comment above runs-on. It now contradicts the code.

Lines 34-35 say "no runner variable may pick the machine". Line 36 now reads vars.CI_TRUSTED_RUNNER. The allowlist limits that variable to ephemeral labels, so this is not a security defect. The comment is still false. Reword it to say that only the allowlisted CI_TRUSTED_RUNNER selector may choose the runner.

CI_TRUSTED_RUNNER selector may choose the runner; remove the contradictory claim
that no runner variable can select the machine.
