Adds a "Be concise" subsection with hard rules (40-word soft cap,
no multi-paragraph bullets, no sub-headers, no probe numbers, no
nested file lists) and a before/after example so the rule is
unambiguous. Calibration tells the author to scan five existing
bullets and match their length.
Existing guidance ("short imperative phrases") was too easy to read
past — concrete commits this session shipped 5-paragraph bullets
crammed with rationale that belonged in the commit body. The new
text closes that loophole.
