feat: add #socketsecurity/lib alias for npm registry version

Added Node.js import map alias to reference the stable published npm
registry version instead of local source files.

## Changes

**package.json imports**:
- Added `#socketsecurity/lib/*` → `@socketsecurity/lib-registry/*`
- This allows scripts and tests to import from the stable npm version
- Example: `import { logger } from '#socketsecurity/lib/logger'`

**devDependencies**:
- Added `@socketsecurity/lib-registry@npm:@socketsecurity/[email protected]`
- Uses npm alias feature to avoid self-reference conflict
- Pinned to specific version for stability

## Usage

Scripts and tests can now choose between:
- `#lib/*` - Local source (in-development, from `./src`)
- `#socketsecurity/lib/*` - Stable npm registry version (published)

This enables testing against the stable release while developing
new features, ensuring backward compatibility.

## Example

```javascript
// Use local in-development version
import { getDefaultLogger } from '#lib/logger'

// Use stable npm registry version
import { getDefaultLogger } from '#socketsecurity/lib/logger'
```
