Review Comment:
### Memoization Missing for Config Builder <sub></sub>
<details>
<summary>Tell me more</summary>
###### What is the issue?
The configuration is being rebuilt from scratch on every call to
buildConfig(), including reading from file system and creating new objects.
###### Why this matters
Each call creates new objects and performs file I/O operations, which can
impact performance if called frequently. Configuration values typically don't
change during runtime.
###### Suggested change ∙ *Feature Preview*
Cache the built configuration using memoization to avoid repeated file I/O
and object creation:
```typescript
let memoizedConfig: ConfigType | null = null;
export function buildConfig(): ConfigType {
if (memoizedConfig !== null) {
return memoizedConfig;
}
const defaultConfig = getDefaultConfig();
const configFromFile = getConfigFromFile();
memoizedConfig = applyEnvOverrides({
port: configFromFile.port ?? defaultConfig.port,
// ... rest of the merging logic
});
return memoizedConfig;
}
```
