fix: prevent Claude bot comments from triggering Claude workflow

Prevents feedback loop where Claude Code Review comments trigger the
interactive Claude workflow, causing spam comments. The interactive
workflow should only trigger on human @claude mentions, not bot comments.

Fixes workflow spam issue seen in PR #1776.
