feat: backfill VisuLogic benchmark integration (LMM-288)

[Luodian]

Summary

• Added a new visulogic task integration under lmms_eval/tasks/visulogic/ with task YAML + utils.
• Implemented VisuLogic image loading from VisuLogic/VisuLogic (data.jsonl + images.zip) and multiple-choice answer extraction for A/B/C/D scoring.
• Updated docs/current_tasks.md to include VisuLogic in the Image Tasks benchmark index.
• Scope check: confirmed no existing VisuLogic task coverage in this worktree before implementation (glob '**/*visulogic*' and repo grep returned no matches).

Validation

• uv run python -m lmms_eval --tasks list
  • Result: task list includes visulogic.
• uv run python -m lmms_eval --model dummy_video_reader --model_args response=A,fail_on_missing=false --tasks visulogic --limit 8 --batch_size 1
  • Result: completed successfully; output metric table includes visulogic_acc = 0.125 for the smoke slice.
• uv run pre-commit run --all-files
  • Result: black passed, isort passed.
• uv run python -m unittest discover -s test/eval -p "test_model_registry_v2.py"
  • Result: command completed successfully (Ran 0 tests, OK).

Sample Output

Sample 1 (doc_id: 0)

• Input: From the four given options, select the most suitable one to fill in the question mark, so that a certain regularity is presented: ↵ ↵ ↵ ↵ A: A ↵ B: B ↵ C: C ↵ D: D ↵ Answer with the option letter only.
• Model Output: To determine the most suitable option, we analyze the pattern in the given figures: ↵ ↵ ↵ ### Step 1: Identify the pattern in the left set ↵ The left set consists of three figures. The first figure is a square with two intersecting diagonal lines (dividing the square into 4 regions). The second
• Reference: A
• Scores: visulogic_acc = 0.0
• Tokens: output=5177, reasoning=5113

Sample 2 (doc_id: 1)

• Input: From the four given options, choose the most suitable one to fill in the question mark, so that it presents a certain regularity: ↵ ↵ ↵ A: A ↵ B: B ↵ C: C ↵ D: D ↵ Answer with the option letter only.
• Model Output: To determine the pattern, we analyze the left and right sets of figures: ↵ ↵ ↵ ### Left Set Analysis ↵ - First figure: Two triangles overlapping, forming a shape with 5 edges. ↵ - Second figure: Two squares intersecting, forming a shape with 8 edges. ↵ - **Third figure
• Reference: D
• Scores: visulogic_acc = 0.0
• Tokens: output=4287, reasoning=4223
