Closing this instance — not a problem with the standardization itself.

This is part of the broader estate-standardization campaign, which has landed cleanly on the large majority of repos. On this repo the branch (estate-standardization-20260607) was cut from an older base and main moved on in the meantime, so it can't merge as-is here:

• Conflicting with current main.
• Stale vs main — a handful of its modified files would roll back newer main state (e.g. dogfood-gate.yml would take actions/checkout back from @v7.0.0 to @v4).
• A few changes (PMPL→MPL relicensing, copyright-header touches) are best applied via the normal manual licence pass rather than bundled here.

Rather than rebase this stale branch, the wanted pieces are being re-applied fresh against current main. First of those — the governance docs — landed in #34, with the dual MPL-2.0 / CC-BY-SA-4.0 header follow-up in #35. Branch left intact for reference.
