/**
 * Custom error hierarchy for typeCAD.
 * Provides structured error types for different failure modes.
 *
 * Adopted across the codebase: ComponentError (component.ts, buses.ts),
 * RoutingError (pcb.ts, pcb_autoroute.ts, pcb_routing_core.ts, pcb_routing_helpers.ts,
 *   pcb_track_builder.ts, length_matcher.ts),
 * BoardCreationError (pcb_board_creation.ts, pcb_footprint.ts),
 * KiCadNotFoundError (kicad.ts, kicad_commands.ts),
 * TypeCadError (schematic.ts, source_inspector.ts, pad_resolver.ts).
