Zsh: select generated files with (om[1]) glob qualifiers

Zsh glob qualifiers like (om[1]) can select the most recently modified file matching a pattern, eliminating the need to copy generated filenames between commands. The qualifier 'o' sorts matches, 'm' orders by modification time (newest first), and '[1]' selects only the first result. This technique streamlines workflows involving tools like memray that generate files with unpredictable names (like process IDs), allowing multi-step processes to be combined into efficient one-liners.
