Adom TSCI - Tscircuit Board Viewer

Trigger words: tscircuit preview, adom-tsci, tsci dev webview, preview tscircuit, interactive tscircuit viewer, inspect board, hover chip info, what is this chip, pcb inspect tool, measure pcb distance, measure between pins, tscircuit hot reload, rerun autorouter, re-run autorouter, walkthrough demo, board walkthrough, sharper silkscreen, bump texture resolution, tscircuit 8192, upgrade tscircuit, stale tscircuit deps, hide chip see traces, AI-driven 3D pcb viewer, usb-c, type-c, UsbCReceptacle, place usb-c, rotate usb-c. Interactive tscircuit preview inside a Hydrogen webview panel ("Tscircuit Board Viewer"). First-class 3D / PCB / Schematic tabs rendered from the tscircuit build output, plus: an Inspect tool (hover any chip / pad / hole / via / silkscreen / board and get a labelled info card with refdes, footprint, net routing, stackup — all from circuit.json), a Measure tool (Fusion 360-style smart picking, mm/inches/mils), a Walkthrough Demo (guided 10-step 3D flyover tour), a one-click Re-run autorouter, a background stale-deps check, and a --texture-resolution N flag that re-bakes board-surface texture up to 8192x8192 for readable silkscreen at zoom. The 3D viewer is fully AI-drivable: every toolbar action has a CLI subcommand, HTTP endpoint, JS eval channel, and console forwarder. Use when the user asks to preview a tscircuit project, inspect board features, measure pin-to-pin distances, start a walkthrough demo, re-run the autorouter, bump silkscreen resolution, or upgrade tscircuit packages. Also routes the `adom-usbc` child guide (`adom-tsci/guides/adom-usbc.md`) for USB-C placement, rotation math, and the canonical `UsbCReceptacle` wrapper.
