chore(schematic): add exploration schematics for boost integration
Capture the working test schematics produced while iterating on the boost-converter integration: firstpcb_test through firstpcb_test5 plus firstpcb_a3 (A3 sheet variant) and firstpcb_nolib (stand-alone copy with no external lib references). Includes ERC reports for the first three test variants. Confidence: medium Scope-risk: narrow Directive: These are exploration artifacts, not the production design - do not edit; treat as historical references
