Adds a figure to exm-convex-intersection: the unit disk's outline, the closed half-disk (its intersection with the half-plane x1 ≥ 0) shaded, and the half-plane's edge. R (ggplot2) and Python (matplotlib) tabs, nested in and cited from the example.

Part of #646.

Files:

• _subfiles/vector-calc/_fig-convex-intersection.qmd (new)
• _subfiles/vector-calc/_exm-convex-intersection.qmd

Rendered optimization-convexity.qmd locally and checked the R figure.

The PR adds a convex-intersection figure with R and Python tabs and includes it in _exm-convex-intersection.qmd. I found no blocking issues. I did not render the page or run any build.

Checks that passed

• Cross-reference targets: #def-half-space, #thm-convex-intersection and #def-unit-ball all exist.
• Figure conventions: the new fig file follows _fig-convex-set.qmd, which sits beside it. That means a panel-tabset with group="language", fig-alt on both chunks and a trailing caption paragraph.
• Include style: the {{< include mds/_subfiles/... >}} path matches how _fig-convex-set.qmd is included in _sec_optimization_convexity.qmd.
• R code: it uses ggplot2:: and tibble:: prefixes and the native |> pipe.
• Macros: the new lines add no math beyond $x_1 \ge 0$ in the caption. That is a coordinate component, not a symbol that has a semantic macro.

Suggestions (non-blocking)

• _subfiles/vector-calc/_fig-convex-intersection.qmd:90: the caption says "of @exm-convex-intersection", but the figure is included inside that example. The self-reference adds nothing and can go.
• _subfiles/vector-calc/_exm-convex-intersection.qmd:14: the figure is nested inside the exm- div, whereas fig-convex-set is included at section level. No rule forbids a figure inside an example, only a theorem-type div inside another. The cross-reference should still render. It is worth a glance in the rendered page that the numbering and caption look right.
• _subfiles/vector-calc/_fig-convex-intersection.qmd:85: the Python chunk ends with plt.show();. The sibling _fig-convex-set.qmd ends with plt.show(). The trailing semicolon is harmless but inconsistent.
• _subfiles/vector-calc/_fig-convex-intersection.qmd:35-45: the R variable names use an ci_..._ci pattern with a suffix on both ends, which reads oddly. They are also split into many single-use intermediates. This matches the no-nested-calls style, so I'm not asking for a change.

I fetched PR #665 live just now. It is open, not a draft and not merged. Its head is 8563dde7c63bb7e090cde18adb9ed02f5d9b4ac1, the commit I reviewed, so the review and its verdict still stand.
