Shadow Arena #008: Yearn yBOLD

Yearn's own yBOLD product on Liquity V2. A multi-strategy allocator across three Stability Pools with auto-compounding. Built on Yearn's TokenizedStrategy V3 framework, the same lineage as the Yearn V2 architecture you build in the Build module. Three findings, all surgical, each mapping to one specific Build section.
