Adds Help > Data Analysis Algorithms, showing docs/CPU_DATA_ANALYSIS.md in a
window. The document is baked into the binary through the Qt resource system
(aliased to :/cpu_data_analysis.md), so it needs no docs/ directory at runtime
and cannot drift from the build it shipped with. Same shape as the existing
third-party licences window, created once and raised thereafter.
Limitation worth knowing: QTextBrowser::setMarkdown renders the headings, lists,
emphasis and inline code well, but it has no math support, so the inline LaTeX in
the more quantitative sections appears as raw "$...$" source. The descriptive
material - which is most of the 744 lines - reads fine. Fixing that properly
means either pre-rendering the document to HTML with a math filter at build time,
or sending the user to the Read The Docs copy instead; neither seemed worth doing
without knowing which you would prefer.
