Evaluate the thecodingmachine/phpstan-strict-rules dev dependency

[TravisCarden]

• Part of Evaluate dev dependencies #78.

Dependency	thecodingmachine/phpstan-strict-rules
Description	A set of additional rules for PHPStan based on best practices followed at TheCodingMachine
Value/justification	High: In addition to various defensive programming rules, it enforces important error-handling standards.
Usage/popularity	Medium. Currently over 2.7M installs and 250 dependents on Packagist.
Security policy	Apparently none. Requested one at thecodingmachine/phpstan-strict-rules#65.
Maintainance	Not especially active but stable. Latest release, v1.0.0, in November, 2021.
Considerations	It catches a mistake made several times in the early days of Composer Stager development of not including a caught exception via the $previous argument in a try...catch block, losing important debugging information.
