Compute a Boost Mystery's mastery-level contribution to its associated skill,
following the Mastery Boost algorithm:
Existing skill: all N boosts compound off the skill's seeded mastery
level; the contribution is the resulting EML delta.
Absent skill: the first boost opens the skill at its Skill Base and the
remaining N − 1 compound off that; the skill is conferred at the result.
The computation is derived state — a caller re-runs it every prepare cycle and
contributes the result as a live delta, so the effect reverts automatically
when the Mystery lapses.
