Parses TV show and movie filenames to extract the title plus season/episode info or release year. Captures the name in 'Fname' (everything up to a period), 'se'/'ep' for S01E05-style markers, 'season' for ranges like S01-S05, and 'yr' for a 4-digit year not followed by 'p' (skipping 1080p/720p resolution tags). Useful for media library organization, renaming scripts, and metadata scraping.
