Breaking Change Analysis

Result: No breaking changes detected

Reasoning: PR #3313 ("docs: update CHANGELOG.md for 0.62.0") is a documentation-only change. The prepared diff shows the sole modified file is CHANGELOG.md, and the change is purely additive (the deleted-lines.txt artifact is empty). It only inserts the 0.62.0 release-notes section. While that inserted text describes breaking changes that originated in other PRs (#3292, #3289, #3301, #3297, #3308), PR #3313 itself does not modify any source code, Jinja2 templates, CLI options, Python API, default values, runtime behavior, supported Python versions, or error-handling logic. A changelog/documentation update does not itself break existing users, so this PR contains no breaking changes.
