fix(docs): correct hero and origin story claims for accuracy

Hero: "identical output for identical input under any load" was too
broad — determinism covers frontier ordering, artifacts, and replay,
not performance timings. Changed to "same seed produces identical
frontier ordering, identical artifacts, and identical replay."

Origin story: removed "twelve hours" and "one afternoon" claims
which misrepresented the actual multi-session timeline. Changed to
"see what happens" without a specific time claim.
