Thinking selector fix: - Replace hardcoded 50-character borders with DynamicBorder component that adjusts to viewport width - Prevents crash when terminal is resized narrow Text/Markdown rendering fixes: - Fix Markdown wrapSingleLine to check if adding next character would exceed width BEFORE adding it (was checking AFTER, causing lines to be 1 character too long) - Add word truncation in Text component for words longer than contentWidth (prevents long unbreakable words from exceeding width) These fixes prevent "Rendered line exceeds terminal width" errors.
