fix: add missing type definitions for market_protection and KiteTickerParams root

[ManikLakhanpal]

This PR fixes two missing type definitions in the published .d.ts files that were left out of sync with their internal interfaces.

Fix 1 — market_protection in placeOrder and modifyOrder (types/connect.d.ts)

market_protection was added to interfaces/connect.ts (PlaceOrderParams and ModifyOrderParams) in #118, but the inline param types in types/connect.d.ts were not updated. TypeScript consumers who pass market_protection get a type error even though the runtime accepts it.

Fix 2 — root in KiteTickerParams (types/ticker.d.ts)

root is already in interfaces/ticker.ts and read by lib/ticker.ts (params.root || 'wss://ws.kite.trade/'), but was missing from the published types/ticker.d.ts, causing a type error for consumers who pass a custom WebSocket endpoint.
