<connector> and <pinheader> components generate non-standard KiCad lib_ids, resulting in "?" symbols in schematic

[tommyhzx]

When using and components in tscircuit, the generated KiCad schematic shows question marks (?) instead of proper symbols. This happens because circuit-json-to-kicad generates non-standard lib_id values that don't exist in KiCad's standard symbol libraries.

1.Create a tscircuit project with a or component:

// Example: USB-C Connector
<connector
name="PWR_USB"
manufacturerPartNumber="USB-TYPEC"
pinLabels={usbCPinLabels}
footprint={...}
/>

// Example: Pin Header

2.Build the circuit and export to KiCad
3.Open the generated .kicad_sch file in KiCad
