Feature: Set output for run results for easy historical analysis

Foundry CI Analysis

Tracking metrics for monitoring both foundry regressions and contract development should not be hard.

It is desirable to monitor and track metrics such as:

bundle size
build time
lines of code
number of dependencies (i.e. import statements)
benchmarks
code coverage

Save run results

Something like this (pseudo code for illustration)

function outputResult(runResult: RunResult) {
    const result = normalizeResult(runResult);

    setOutput('success', result.success);

	// Build Related
    setOutput('number_of_contracts_compiled', result.number_of_contracts_compiled);
    setOutput('compiletime_of_contracts_compiled', result.compiletime_of_contracts_compiled);

	// Testing related
    setOutput('number_of_contracts_checked', result.number_of_contracts_checked);
    setOutput('number_of_issues', result.number_of_issues);
    setOutput('number_of_contracts_with_issues', result.files_with_issues.length);
    setOutput('contracts_with_issues', normalizeFiles(result.files_with_issues));
    setOutput('result', result);
}

The build related metrics should be applicable to all repos, as opposed to the testing related, which would ofc require tests (notwithstanding tests that are 'correct').
