inductor drops maxCurrentRating: prop and schema field both exist, value never written

What happens

maxCurrentRating is declared on InductorProps and max_current_rating exists on the simple_inductor circuit-JSON schema, but Inductor never writes it — the value is silently dropped:

<inductor name="L2" inductance="10uH" maxCurrentRating="2A" />

{
  "type": "source_component",
  "ftype": "simple_inductor",
  "name": "L2",
  "inductance": "10uH",
  "display_inductance": "10µH"
}

No max_current_rating anywhere in the output.

Both ends already exist

// @tscircuit/props — InductorProps
maxCurrentRating?: number | string;

// circuit-json — source_component, ftype "simple_inductor"
max_current_rating: z.ZodOptional<z.ZodNumber>;

So this is purely a missing hand-off in Inductor.doInitialSourceRender(), which inserts inductance, display_inductance, supplier_part_numbers, manufacturer_part_number and display_name, but not the rating. Anything downstream reading max_current_rating (BOM export, part selection, DRC on current limits) sees nothing, with no warning that the prop was ignored.

A wrinkle worth flagging for whoever fixes it

maxCurrentRating has no zod transform, unlike capacitor's maxVoltageRating:

capacitor: maxVoltageRating: z.ZodOptional<z.ZodEffects<...>, number, string | number>>  ← converts to number
inductor:  maxCurrentRating: z.ZodOptional<z.ZodUnion<[z.ZodString, z.ZodNumber]>>        ← raw

So the raw string reaches the component and a naive parseFloat("500mA") yields 500, not 0.5 — off by 1000×. parseSiUnit doesn't work either (it returns NaN for "2A", since it doesn't expect a unit suffix); parseAndConvertSiUnit(...).value handles both:

"2A"    → 2
"500mA" → 0.5
"1.5A"  → 1.5
"2"     → 2
"abc"   → NaN

How I found it

Cross-referenced every *Props interface in @tscircuit/props against the props each component actually reads. Other hits from the same sweep that may or may not be intentional: Capacitor.bypassFor/bypassTo/schSize, Resistor.schSize/tolerance, Board.topSolderMaskColor/bottomSolderMaskColor/doubleSidedAssembly, Chip.internalCircuit/pinCompatibleVariants. I'm only filing this one because it's the one where the destination schema field already exists, so the fix is unambiguous.

PR ready.

Start in Inductor.doInitialSourceRender(), then compare its existing property hand-offs with capacitor's maxVoltageRating handling. Verify that maxCurrentRating reaches max_current_rating with correct SI-unit values, including 2A, 500mA, 1.5A, 2, and invalid input; done means the circuit-JSON output contains the rating.
