fix: Prevent get_the_excerpt() from triggering the_content filter

Browse Source 
- get_the_excerpt() internally calls the_content filter when generating auto-excerpts
- When in shortcode context, now uses raw post_excerpt or wp_trim_words() instead
- This was the remaining recursion path causing memory exhaustion
