Review: PR #1166 — docs: clarify demonstrative pronouns and improve narrative flow

Scope: purely prose edits across 4 subfiles, replacing bare "This"/"That" with an explicit noun phrase, directly implementing the CLAUDE.md rule: "Always add a noun phrase after 'This', 'That', and 'Those' to clarify the referent." No math, code, or config changes.

Per-file check

• _subfiles/Linear-models-overview/_exr-linreg-rescaling.qmd:10 — "This includes the intercept" → "These affected parameters include the intercept". Correct referent (coefficients affected by the interaction), grammatically sound with the following list.
• _subfiles/Linear-models-overview/_sec_hers_lm_diagnostics_lm2.qmd:23 — "This previews…" → "This similarity previews…". Correctly refers back to the near-identical residual/QQ plots described in the preceding sentence.
• _subfiles/Linear-models-overview/_sec_linreg_model_selection.qmd:36 — "That helps us decide…" → "That structure helps us decide…". Correctly refers to the DAG's encoded time-ordering/causal structure from the prior sentence.
• _subfiles/proportional-hazards-models/_sec-competing-risks.qmd:49 — "This overestimates…" → "This naive Kaplan-Meier approach overestimates…". Correct referent. Minor optional nit: "naive" is now used in two consecutive sentences ("A naive approach treats..." / "This naive Kaplan-Meier approach overestimates...") — slightly repetitive, but not incorrect or ambiguous; not blocking.

Other checks

• No math was added or changed, so there's nothing to verify against latex-macros/macros.qmd (submodule present at latex-macros/, confirmed via .gitmodules) — no macro simplification or new-macro candidates apply to this diff.
• No hallucination risk: no new function/API/citation/URL references introduced.
• No structural/_quarto-*.yml changes, no subfiles added, no heading rule implications.
• One-source-line-per-phrase convention preserved on every changed line.
• No prior Claude review exists on this PR (only the Jules bot's automated intro comment) — this is the first review round.

No blocking issues found.
