fix(rules): set the slumber hex duration to the witch level

PF1e (APG Slumber): the target "remains asleep for a number of rounds equal to the witch's level" (Will negates). _hex_slumber hardcoded 1 round; it now uses the caster's level. The RAW clause that the hex ends when the target takes damage is not modeled (no wake-on-damage hook in the engine) — documented in README. Two behavioral tests pin the failed-save duration (= level) and the saved case.
