data(mobile): import Kaggle smartphone and SoC seeds

[Seungpyo1007]

Summary

• import Kaggle smartphone seed records across Honor, OPPO, vivo, OnePlus, Infinix, Tecno, Motorola, Lenovo, and related brands
• import Kaggle mobile SoC benchmark seed records for MediaTek, Qualcomm, Huawei/Kirin, Samsung/Exynos, and Unisoc
• keep all newly imported records verified: false
• exclude tablet-like rows from the smartphone catalog before publishing
• regenerate the public mobile/SoC dump so /v1/socs and /v1/smartphones reflect the new records

Dataset impact

• SoCs: 123 -> 195 (+72)
• Smartphones: 367 -> 734 (+367)
• Total public records: 6,626 -> 7,065 (+439)

Sources

• Kaggle abdulmalik1518/mobiles-dataset-2025 (Apache-2.0)
• Kaggle devgondaliya007/smartphone-specifications-dataset (Apache-2.0)
• Kaggle alanjo/smartphone-processors-ranking (CC0-1.0)
• Excluded sady36/mobile-phones-specs because the downloaded metadata did not expose a clear license

Commit structure

• SoC imports split by manufacturer group
• Smartphone imports split by brand/group
• SoC process-node service compatibility fix split separately
• Public dump regeneration split separately

Verification

• python -m app.validate
• python TechEngine\integrity_check.py data --strict
• git diff --check
• cd site && npm.cmd run build

Closes #1
