Citations: add "Copy-paste with caution" section (closes #5)

[d-morrison]

Summary

Adds a Copy-paste with caution section to the Citations and Evidence chapter (citations-evidence.qmd), placed after "What makes a source trustworthy".

Content (#5)

• Don't copy-paste prose from non-coauthors of the current document; mark any verbatim reuse as a direct quotation and cite it.
• Prefer paraphrasing over quoting — it reads better and shows understanding.
• Avoid recycling your own published text (self-plagiarism); cite the earlier work instead.
• Cross-reference duplicated material rather than repeating it — a single source of truth that also improves concision (the secondary point raised in the issue).

Conventions followed

• New ## section inserted without altering existing prose; semantic line breaks, blank lines before lists; no new external links. Verified with quarto render --to html.

Note on issue #4

While working this cluster I found that #4 ("citations needed for every claim, unless direct evidence") is already fully implemented — it is the entire premise of this chapter (added in #15). I've left a comment on #4 recommending it be closed as already-addressed rather than duplicating content here.

Closes

Closes #5.

Overall the PR is clean: valid .qmd syntax, semantic line breaks throughout, blank line before the 3-item bullet list (per CLAUDE.md convention), front-matter output-file stems are untouched, no _site//_freeze/ artifacts, no new dependencies.

Two small prose issues flagged inline:

1. L147–151 — The intro paragraph counts "two problems" from copying another writer's words, but the third bullet covers self-plagiarism. The count or scope should align.

2. L168–172 — The cross-referencing paragraph is effectively a fourth guideline that floats outside the bullet list; a transitional phrase or promotion to a fourth bullet would improve scannability.

Both are minor. If you want to address them:

Both flagged issues are resolved in the latest commit:

Comment 1 (lead-in scope) ✅ — The intro no longer says "two problems" or limits scope to "another writer's exact words". It now reads:

Copying exact wording —
whether from another writer or from your own earlier work,
and even with a citation —
can cause problems: …

This correctly covers both external copying and self-plagiarism before the third bullet introduces the latter.

Comment 2 (cross-referencing paragraph) ✅ — The paragraph now opens with a clear transitional phrase (A related case is repetition *within* your own document.) that signals the scope shift before giving the guideline, matching suggestion A from the earlier review.

Everything else remains clean: semantic line breaks, blank line before the 3-item bullet list, no _site//_freeze/ artifacts, no new dependencies or external links. The section is structurally coherent and ready to merge.
