Add multiple layers of defense against misclassified wisps:
- Importer auto-detects -wisp- pattern and sets ephemeral flag
- GetReadyWork excludes -wisp- IDs via SQL LIKE clause
- Doctor check 26d detects misclassified wisps in JSONL
This addresses recurring issue where wisps with missing ephemeral
flag would pollute bd ready output after JSONL import.
