* fix(memory-core): filter REM dreaming candidates to light-staged entries
REM dreaming re-ingested the full short-term recall store independently,
ignoring which entries were staged by the light sleep phase. Because the
confidence formula heavily weights accumulated averageScore (45%) and
recallStrength (25%), old high-recall entries permanently dominated
freshly staged candidates. The intended light→REM→deep pipeline was
broken: light correctly staged current material, but REM selected a
different set entirely, so lightHits never paired with remHits for deep
ranking.
Fix: in runRemDreaming(), read the phase-signals store for keys with
lightHits > 0 and filter entries to that set before passing to
previewRemDreaming(). When no light-staged keys exist (light disabled
or first run), fall back to the full entry set for backward
compatibility.
Added readLightStagedKeys() to short-term-promotion.ts as a clean
export for reading the light-staged key set from the phase signal store.
