fix: Sync binary version with package.json dynamically

[adambkovacs]

Summary

• Fixed binary-manager.ts to dynamically read version from package.json instead of hardcoding
• This ensures npm package version stays in sync with GitHub releases
• Prevents "binary not found" errors when package version is bumped

Problem

The npm package was at version 1.2.1 but binary-manager.ts had BINARY_VERSION = 'v1.0.2' hardcoded, causing download failures for platforms like aarch64-apple-darwin.

Solution

// Before (hardcoded, out of sync):
const BINARY_VERSION = 'v1.0.2';

// After (dynamic):
import { version as PKG_VERSION } from '../package.json';
const BINARY_VERSION = `v${PKG_VERSION}`;

Test plan

• Verify TypeScript compiles with resolveJsonModule: true (already enabled in tsconfig.json)
• Test binary download after next release is published
