Add 124 missing Intel Xeon, Celeron and Pentium CPUs from Wikipedia sub-pages

[Seungpyo1007]

124 Intel CPUs that were missing from data/cpu/intel, from the per-family Wikipedia lists. Wikipedia split List of Intel Xeon/Core processors into sub-pages: the Xeon (Broadwell … Rocket Lake)-based pages, Core mobile, Celeron and Pentium.

Group	Count
Xeon Scalable / W-3200/3300 / D-2100 (Skylake, Cascade Lake, Ice Lake)	88
Xeon E3 v6, E-2200/2300, W-1200/1300, Broadwell D/E5/E7	14
Celeron / Pentium Gold embedded and mobile	22

• verified: false; each record cites its sub-page.
• Architecture:
  • Xeon records take the microarchitecture from the page (e.g. "Cascade Lake"), not the placeholder "Xeon" many older records use.
  • Others use the table's codename.
• Only rows with an explicit thread count are imported. The parser used to copy a bare "Cores" value into threads (fixed in Parse multi-row headers in the Wikipedia GPU ingest TechEngine#91). That drops about 470 rows, mostly older Xeons, until a thread-count source is added.
• Skipped:
  • Alder Lake-U hybrid Celeron/Pentium: the table counts only P-cores.
  • The Pentium Gold G5600E: listed as 2C/2T, which is doubtful for a Pentium Gold.
  • Family rows ("Core Ultra X9").
  • Slugs whose variant rows conflict.
• Spot-checked against known specs: Gold 6209U (20C/40T, 2.1 GHz, 27.5 MB, 125 W), D-2191, W-3365, Pentium Gold 4415U.

python -m app.validate passes. Dump refresh will follow in the combined dump PR.
