chore: sync public mirror from internal

[evalops-mirror]

Summary

• sync the sanitized public tree from dx-corp/mono
• keep dx-corp/code as a generated public mirror of the private source of truth
• preserve public-owned CI and trusted-publishing workflows from the public checkout
• internal source SHA: 286d0a37ebf99fa22738837904ad8e9f2b3b111b
• last generated public sync base: 286f11a74b63db13a1acd5b4734a431f224e002c
• previewed public-tree drift: 125 file(s) to copy/update and 0 stale file(s) to delete
• public-only commits since last generated sync: 0
• to pause generated syncs while hand-editing this branch, apply the sync-hold label to this PR; the sync workflow skips every push while it is set

Public-only commits since last generated sync

• none detected since last generated sync

Validation

• generated by the sync-public-release-mirror workflow in public-tree mode

Test Plan

• generated by the maestro-sync-public-release-mirror workflow in public-tree mode
• public-source-provenance require-internal-pr confirms internal source PR lineage
• generated mirror PRs use the slim public CI path (fmt/clippy/smoke + provenance); full cargo test/evals already ran on internal main for this SHA
• bot review threads on generated mirror PRs are advisory and do not block the next sync update

Staged Rollout

• Staging is unnecessary for this generated mirror PR: it does not independently promote user-visible behavior. It mirrors already-reviewed internal source from dx-corp/mono@286d0a37ebf99fa22738837904ad8e9f2b3b111b, including existing hidden/evaluation surfaces, and keeps public package parity behind the established public-source-provenance gate.
