memory-search: add --query mode and prompt key boost

Browse source 
Two changes:

1. New -q/--query flag for direct search without hook machinery.
   Useful for debugging: memory-search -q inner-life-sexuality-intimacy
   shows seeds, spread results, and rankings.

2. Prompt key boost: when the current prompt contains a node key
   (>=5 chars) as a substring, boost that term by +10.0. This ensures
   explicit mentions fire as strong seeds for spread, while the graph
   still determines what gets pulled in.
