Add ShopifySovereignBridge for Robert biometric cart sync and inventory adjustment

[Copilot]

Implements ShopifySovereignBridge — a class bridging the Robert biometric engine with Shopify's Admin API to inject fit-score metadata into draft orders and propagate Armario Solidario stock changes.

Changes

api/shopify_bridge.py

• ShopifySovereignBridge.__init__(api_key, shop_url) — normalises shop_url (strips scheme/path), builds api_base against SHOPIFY_ADMIN_API_VERSION (default 2026-04), and sets auth headers.
• sync_robert_to_shopify(look_id, engine_metrics) — POSTs a draft order with Robert_Fit_Score and Biometric_Validation line-item properties; returns the invoice_url from the response, a fallback label, or None on failure.
• update_inventory_physics(fabric_key, stock_change) — calls inventory_levels/adjust.json mapping fabric_key → inventory_item_id with location_id read from SHOPIFY_LOCATION_ID env var; returns bool success.

tests/test_shopify_bridge.py (new)

19 unit tests covering init URL/header construction, draft-order payload shape, HTTP error and exception paths, and inventory adjustment payload mapping.

Usage

bridge = ShopifySovereignBridge(api_key=os.environ["SHOPIFY_ADMIN_ACCESS_TOKEN"],
                                 shop_url="mystore.myshopify.com")

# Inject Robert fit score into a Shopify draft order
url = bridge.sync_robert_to_shopify(look_id=variant_id, engine_metrics={"fitScore": 94})

# Sync stock when Armario Solidario withdraws a garment
# Requires SHOPIFY_LOCATION_ID env var (numeric Shopify location ID)
bridge.update_inventory_physics(fabric_key="inventory_item_id_here", stock_change=-1)
