PHPStan Baseline

When to use

• The user wants to adopt PHPStan on an existing legacy codebase that already has many type errors, without blocking on a full cleanup.
• The user wants to generate a PHPStan baseline to snapshot existing errors so a new level can pass without fixing everything first.
• The user wants to shrink the PHPStan baseline over time, or keep it from growing, as they pay down type debt.
