Skip MethodChainingNewlineFixer in boolean and comparison chains

[TomasVotruba]

Fixes #49

MethodChainingNewlineFixer newlined any single-line )->method() chain, including ones used as boolean or comparison operands. This split readable conditions like:

if (
    $paramType->isInteger()->yes()
    || $paramType->isBoolean()->yes()
) {

into an uglier form with ->yes() pushed onto its own line.

Change

• ChainMethodCallAnalyzer::isPartOfBooleanOrComparison() scans left and right from the -> at the chain's own bracket depth (skips nested ()/[], stops at the enclosing bracket, ;, {, }). Returns true when a boolean (&&, ||, and, or, xor) or comparison (===, !==, ==, !=, <=>, <=, >=, <, >) operator sits at that depth.
• MethodChainingNewlineFixer skips the newline when the chain is such an operand.

Plain chains, assignments, and arg/array chains are unaffected - still newlined as before.

Added two skip fixtures covering both examples from the issue.
