Refactors 08-sb-active-use-plan.md into two focused plans following a
design session that diagnosed separate content and findability problems.
Plan A (09): note types (convention/reference/howto), templates, value
gate, two-layer write mechanism, and vault population build order.
Plan B (10): vault-index.json, /memory-find skill, SessionStart
injection, and SessionEnd agent for self-evolving knowledge capture.
08 is retained with a superseded notice linking to the new plans.
