fix: expose About subsection headings

[corwinm]

Summary

• promote Technologies I love and Currently building toward from styled paragraphs to semantic h3 headings
• expose the two About subsections to assistive-technology heading navigation beneath the section’s h2
• preserve the existing typography, spacing, icons, lists, and two-column layout
• extend the About regression tests to enforce the heading hierarchy

TDD

• RED: the focused test failed because both labels were still rendered as paragraphs
• GREEN: the focused test passes with both labels rendered as h3 elements

Validation

• pnpm lint — passed with 0 warnings and 0 errors
• pnpm typecheck — passed
• pnpm test — 45/45 passed across 13 files
• pnpm build — passed
• git diff --check — passed
• production accessibility tree exposes both About subsection labels as level-three headings
• computed styles remain 16px and font weight 600 for both labels
• independent pre-commit review passed with no security concerns or logic errors

Scope

This is a semantic accessibility improvement only; visible About-section styling and layout are unchanged. The separate resume-refinement worktree and its uncommitted files were not modified.
