P1: Gate message asked for raw production data records — changed to
"redacted or synthetic values" to prevent sensitive data exfiltration
P2: SKILL.md description now includes MultiEdit (was missing after
MultiEdit gate was added in previous commit)
P2: Session key pruning now caps __prefixed keys at 50 to prevent
unbounded growth even in theoretical edge cases
9/9 tests pass.
