pub fn collect_with_truncation(

    new_content: &str,
    max_size: usize,
    truncated: &mut bool,
) -> bool

Collect content with lazy truncation (Codex pattern). Marks truncated but continues draining to prevent pipe blocking.

• new_content - New content to append
• max_size - Maximum allowed size
• truncated - Mutable flag tracking truncation state

Returns

true if content was appended, false if truncated
