• This PR looks low risk to merge: the only reported issue is a low-severity documentation mismatch (2/10) rather than a functional defect.
• In node-graph/nodes/text/src/lib.rs, a comment appears to describe the opposite of if use_joiner, which can mislead future maintenance but should not change runtime behavior by itself.
• Pay close attention to node-graph/nodes/text/src/lib.rs - update the contradictory comment so the control flow intent is clear.

P3: This comment contradicts the condition (`if use_joiner`) and describes the opposite behavior, which makes the control flow misleading.

Code Review

This pull request introduces a new String Capitalization node, enabling various casing styles such as Headline, Sentence, and Camel case, with optional word joining using custom separators. Additionally, the string_slice and string_length nodes have been updated to use grapheme clusters for improved accuracy, and slice indices were transitioned from floating-point numbers to integers. Review feedback highlighted a compilation error in the string_slice logic caused by type mismatches and recommended normalizing character casing in the manual CapitalCase implementation to ensure consistency across different modes.
