docs: add resource prep section and sync docker/bash helpers
- Rewrite myread.md with proper markdown and four download sources:
code, data, evalscope-complete-py312 image, execution images.
- Add bash/collect_results.py, perf_backup.py, pull_swe_bench_images.py
for result aggregation, breakpoint perf recovery, and SWE-bench
image pre-pulling.
- Update bash/run.py with multi-run suites, perf backup/restore, and
whitelist-based summary.
- Update config/dpv4-int8_nothinking.yaml benchmark parameters.
- Ignore /docker_images and /results in .gitignore.
