Trim Comments

Reduce comment noise. normal (default) shortens wordy comments but keeps their meaning — shorter, not cryptic; never deletes. aggressive deletes nearly every comment. Use aggressive only when the user says so ("aggressive", "strip", "remove all").

Two rules always hold:

• Edit comments only — never change a line of executable code.
• Scope: unless the user names files, trim only changed code — the uncommitted local diff first, then the PR diff. Touch the whole codebase only when explicitly asked.
