Handler Implementation Notes

Issues Found in Current Handler

HashSet usage (line 61): Should use Set.of() or EnumSet for immutability
Missing TRANSISTOR in getSupportedTypes(): Patterns exist for 2SC/2SA but type not in supported set
Missing base IC type in getSupportedTypes(): Patterns for IC (IGBTs, motor drivers, optocouplers) exist but base IC not declared
Package extraction incomplete: Only handles TPC/TPH/TMP, missing TK, TLP, SSM, TB, 2SC/2SA series
Series extraction incomplete: Missing TLP, 2SC, 2SA, TB series extraction
