data(cpu): fill process node, L3 cache and boost clock for 581 CPUs

[Seungpyo1007]

What

581 CPU records gain 982 previously-null fields — process_node 400, l3_cache_mb 580, boost_clock_ghz 2 — from the Wikipedia CPU list pages (Intel Core desktop/mobile, AMD lists).

Coverage moves: process_node 24% → 34%, l3_cache_mb 19% → 34%.

Why this source

3,001 of 3,977 CPUs are bulk stubs: schema-complete, values null, and their architecture holds a brand family ("Xeon", "Core") rather than a microarchitecture — so the node is not derivable inside the dataset (Xeon alone spans 250 nm to 5 nm). An external, citable source was required. The Wikipedia list pages carry the codename + lithography in the section heading and L3/clocks per row, and are not bot-blocked.

How correctness was enforced

These tables do not share a column layout (some carry an extra iGPU / GPU-clock column), so a positional read silently shifts values. An early pass produced L3 = 95 MB (actually the TDP column), TDP = 2011 (the release year), and L3 = 4600 (the "HD 4600" iGPU). Guards:

1. Columns are located by header name, with rowspan/colspan expansion — never by index.
2. Confirm before write: a row is used only when the data we already hold agrees — base clock within 0.05 GHz and TDP within 1 W. Base clock agreed on 233/234 correct matches, making it a reliable SKU-identity check; TDP disagreement flags a shifted table. 456 unmatched / 7 disagreeing rows were dropped rather than guessed.
3. Plausibility bounds (L3 0.5–64 MB) as a second net.
4. MSRP deliberately not imported — Wikipedia lists launch price, which is not what msrp_usd holds (120 of 129 disagreed; e.g. our i7-860 = $44). Different semantics, not an error to "fix".

Spot-checks against known specs pass: i7-2600K → 32 nm / 8 MB, i3-2100 → 32 nm / 3 MB, i7-4790K → 22 nm / 8 MB / 88 W.

Only empty fields are written; nothing existing is overwritten, verified is untouched, and the sourcing Wikipedia page is appended to source_urls.

python -m app.validate → Data validation passed.

Closes #1

Warning

Tracked verified coverage is below 50% for watch 2.5% (11/433), brand 4.8% (10/207), tablet 5.0% (174/3455), soc 5.8% (123/2104), smartphone 9.1% (8453/93396), all 9.5% (10028/105742), gpu 12.0% (244/2030), pda 19.3% (27/140), and 1 more.
Tracked coverage excludes records missing the verified field; see the Missing verified column for those records.
This does not fail validation. Keep imported records verified: false until manual audit, but treat this as follow-up verification work before relying on the affected categories as curated data.

Validation notes

• Full advisory outlier listings are suppressed on successful runs because they are dataset-wide and mostly stable between PRs.
• Failure runs still include a detailed log excerpt for debugging.
