chore!: forward-merge v4.2-dev into v4.3-dev

[infraclaw-dash]

Issue being fixed or feature implemented

Forward-merge v4.2-dev into v4.3-dev so the newer development branch receives the already-merged fixes, including the runner-image/workflow changes required by the current self-hosted CI environment.

Concrete failure: Kotlin CI for #5146 still runs android-actions/setup-android@v3. It tries to install command-line tools into the root-owned, prebaked /opt/android-sdk and fails with cannot create cmdline-tools — Permission denied, before compilation.

The compatible ordinary-CI workflow is already on v4.2-dev via #4702: select/verify the pinned runner image and use its prebaked SDK instead of mutating it. #5141 fixes a separate release-workflow NDK-path issue; that release-only change did not repair this branch's ordinary Kotlin CI.

What was done?

• Opened the requested full branch forward merge, head infraclaw-dash:merge/v4.2-into-v4.3-20260928, base dashpay:v4.3-dev.
• The head is an exact snapshot of upstream v4.2-dev at the source SHA below, with no additional commits. A dedicated fork branch is used because the author does not have upstream collaborator permission; the protected source/target branches remain untouched.
• This brings the complete upstream branch history, not only CI changes. Application, SDK, protocol and dependency changes already merged into v4.2-dev are also in scope for review.
• No new source changes or conflict resolutions were authored for this PR. No target branch was reset, force-pushed or merged.
• Preserve v4.3-dev-specific changes when resolving conflicts. Prefer an ancestry-preserving merge for branch synchronization rather than squash/rebase, subject to repository policy. Do not resolve target-specific conflicts by changing the shared v4.2-dev branch.

Preflight snapshot:

• Source: 1464314a7a0a543fccda21bed6bcd4521f0eda69
• Target: 67340ad82406cb36147234bc46f6c572c78ecef9
• GitHub comparison: 118 source-only commits, 33 target-only commits; histories have diverged.

How Has This Been Tested?

• Read the exact failed job log and workflow revision.
• Read-only inspection of the actual runner confirmed UID 1001, root-owned SDK directories and non-writable command-line-tools installation paths.
• Compared the ordinary Kotlin workflow on both branches and verified the repair is on v4.2-dev.
• Verified branch direction and checked that no duplicate open forward-merge PR exists.
• Fork-origin self-hosted jobs may be skipped by repository policy; skipped is not a successful build. A maintainer-controlled trusted validation path is needed before claiming the merged workflow works.
• The combined merge result has not been built or tested. Conflict review and fresh CI against the resulting merge are required. This PR is not a claim that every CI or application failure is resolved; rerunning an old captured workflow is not proof of the new one.

Breaking Changes

This full forward merge includes existing upstream breaking changes; it is not a CI-only patch. Review protocol/version-specific behavior against the intended v4.3-dev release line. The PR title is marked accordingly.

Checklist

• Verified source/target direction and investigated the reported CI failure
• Reviewed the complete combined application/protocol diff
• Resolved any integration conflicts while preserving target-specific changes
• Fresh CI passes on the proposed merge result
• Maintainer approval to merge

Superseded by #5151. That PR is an actual merge commit of v4.2-dev into v4.3-dev with the dpns.rs import conflict resolved and a fix for a PV15 build break: v15.rs referenced DRIVE_ABCI_QUERY_VERSIONS_V3, which #5057 removed on v4.2-dev. Its branch is on dashpay, so self-hosted CI can run.
