Function detectPM

detectPM(__namedParameters?: DetectPMOptions): Promise<DetectPMResult>
Detect the package manager used in a project directory.
Parameters
- __namedParameters: DetectPMOptions = {}
Returns Promise<DetectPMResult>
Remarks
Detection strategy:
1. npm_config_user_agent environment variable
2. Lockfiles (package-lock.json, pnpm-lock.yaml, etc.)
3. package.json → packageManager field
Each later step can override earlier detection.
Example
```
const pm = await detectPM();

console.log(pm.name);
// "pnpm"

if (pm.isPnpm) {
  console.log('Using pnpm');
}
```
Example: Disable lockfile detection
```
await detectPM({ lockfile: false });
```
Example: Disable packageJson detection
```
await detectPM({ packageJson: false });
```
