[Auto] Add DEIMv2 to Transformers (cluster-41211-3): merged 1 of 3 PRs

[evalstate]

Cluster: cluster-41211-3
Base: main

Merged:

• model: Add DEIMv2 to Transformers huggingface/transformers#44339 - Canonical cluster PR; fetched and merged cleanly locally; approved and substantially more complete than the older DEIMv2 PRs.

Skipped:

• Add-Deimv2 huggingface/transformers#41291 - Related DEIMv2 PR but not part of cluster-41211-3, so it was not attempted for this cluster merge.

Failed:

• Add DEIMv2 model, image processor, and basic tests huggingface/transformers#41356 - Local merge on top of model: Add DEIMv2 to Transformers huggingface/transformers#44339 produced add/add conflicts in the core DEIMv2 docs, config, modeling, and tests; appears stale and superseded by model: Add DEIMv2 to Transformers huggingface/transformers#44339.

Notes:

• The requested branch did not exist locally; it was created and checked out before merge work began.
• Issue Add DEIMv2 huggingface/transformers#41211 was still open at inspection time, so nothing was skipped due to the issue already being closed.
• After aborting the failed Add DEIMv2 model, image processor, and basic tests huggingface/transformers#41356 merge, the branch was left in a coherent state with only the local merge commit for model: Add DEIMv2 to Transformers huggingface/transformers#44339.
• Pre-existing untracked local agent artifacts remained in the working tree and were not modified.

Next steps:

• Run the relevant DEIMv2 validation and repo checks on the current branch, especially the DEIMv2 slow/integration tests.
• Treat Add DEIMv2 model, image processor, and basic tests huggingface/transformers#41356 as superseded unless a maintainer explicitly wants specific pieces ported over from it.
• Monitor upstream model: Add DEIMv2 to Transformers huggingface/transformers#44339 CI status if needed, since it showed as blocked by pending checks during inspection.
