Description

Follow up on: #154

Fixes integration issues between btcindexer and block-ingestor. Improves type safety by moving shared types to lib and establishing consistent naming conventions.

Type System

• Shared types: Moved BlockQueueRecord, BtcNet, and kvBlocksKey to @gonative-cc/lib/nbtc
• New interfaces: NbtcTxInsertion, NbtcTxUpdate, NbtcBroadcastedDeposit, ElectrsTxResponse for type-safe storage operations
• Naming: snake_case → camelCase for consistency (nbtc_pkg → nbtcPkg, sui_network → suiNetwork, etc.)

Logging

• Centralized logger: Created @gonative-cc/lib/logger with structured JSON output
• Error context: Added logError(ctx, error) utility with method names for debugging
• Removed: errutils.ts in favor of unified logger

Configuration

• Binding names: btc_blocks → BtcBlocks, BlockStore → BtcBlocks (PascalCase consistency)
• Block queue: Added timestamp_ms to BlockQueueRecord for proper block tracking
• Cleanup: Fixed trailing commas in wrangler.jsonc
