Pull request overview

This PR rewrites Chapter 7 to better match the textbook’s treatment of confounding, replacing placeholder material with a fuller causal-diagram-based exposition and updated figures. It fits into the codebase as part of the ongoing transcription/modernization of the Quarto textbook chapters.

Changes:

Reworked chapters/07-confounding.qmd with a new numerical example, revised structural/backdoor-criterion discussion, new DAG-based figures, and an expanded SWIG section.
Removed the prior confounding-adjustment section and replaced it with textbook-aligned material on confounders, collider bias, and SWIGs.
Added new terms to inst/WORDLIST to support spell-checking for the updated chapter text.

Applied all five changes from the review (commit 395324b):

Fine Point callout markup (7.1 and 7.2): Removed separate ### headings and inner ## headings; both callouts now use ::: {.callout-note title="..."} matching the repo convention in chapters/17-causal-survival-analysis.qmd.
Structure II DAG missing U -> Y: Added the U -> Y edge so Structure II now shows a genuine backdoor path ($A \leftarrow L \leftarrow U \to Y$) that is blocked by conditioning on $L$. Updated the caption and the explanation text accordingly.
SWIG L -> a edge: Corrected the SWIG example to remove L -> a. The edge list now correctly shows L -> A (incoming arrows stay on the natural-value half) and a -> Y^a (outgoing arrows leave from the fixed-value half), matching the construction rule just introduced.
pre in WORDLIST: Removed pre from inst/WORDLIST.

Also added *.log to .gitignore to prevent LaTeX log files from being committed.

@copilot resolve the merge conflicts in this pull request

Resolved in commit 4328eb5. The only conflict was in the chapter header — main added {{< include ../latex-macros/macros.qmd >}} to all chapters via PR #66. The resolution keeps the macros include first, followed by our setup R chunk and the full Chapter 7 rewrite.
