Update Magpie floor to 0.9.0.dev202610140816 (#74815)

Contributors whose Magpie plugins are older than this build are asked by
the skills' pre-flight to upgrade, so everyone runs the refreshed
pre-flight checker and secure-setup files the build ships.

The reconciled block records that the project's overrides and
configuration were checked against this build, so the pre-flight stops
proposing a project-wide reconcile sweep to every contributor.
