Update rubocop to 1.86.1

[camilopayan]

Updates RuboCop from 1.84.0 to 1.86.1.
Updates standard-performance to 1.9.0.

New cops

These cops were added and need a configuration decision before tests will pass:

Cop	Description	Recommendation	Rationale	PR
Lint/DataDefineOverride	Checks for Data.define overriding existing methods.	Enable	Prevents subtle bugs in modern Ruby's Data objects by ensuring methods aren't accidentally shadowed.	#14773
Lint/UnreachablePatternBranch	Detects unreachable branches in case patterns.	Enable	This is a safety/lint rule that catches potential bugs in pattern matching, which is highly valuable for code quality.	#14925
Style/EmptyClassDefinition	Enforces consistent style for empty classes.	Enable	Promotes consistent coding style for empty classes, which aligns with Standard's goal of eliminating bikeshedding.	#14961
Style/FileOpen	Checks for File.open without a block.	Enable	Encourages safe resource management by ensuring files are closed, which is a strong safety improvement.	#14942
Style/HashLookupMethod	Enforces preference between Hash#[] and Hash#fetch.	Ignore	This is often a matter of context-specific preference (safety vs brevity) and enforcing one globally can cause high friction.	#14977
Style/MapJoin	Suggests more efficient alternatives to map { ... }.join.	Enable	Promotes more efficient and idiomatic Ruby patterns, which aligns with Standard's modernization goals.	#14939
Style/OneClassPerFile	Enforces one class per file.	Ignore	While generally good practice, it can be too restrictive for small utility classes or data structures, leading to excessive file proliferation.	#14924
Style/PartitionInsteadOfDoubleSelect	Suggests partition instead of two select calls.	Enable	Improves performance and readability by avoiding double iteration over collections.	#14923
Style/PredicateWithKind	Checks for predicate methods used with kind_of? or is_a?.	Enable	Encourages idiomatic predicate usage, improving code consistency and readability.	#14811
Style/ReduceToHash	Encourages each_with_object or to_h instead of reduce.	Enable	Encourages more readable and idiomatic alternatives for hash building.	#14938
Style/RedundantMinMaxBy	Detects redundant min_by or max_by calls.	Enable	Removes redundant code, aligning with the principle of simplicity.	#14812
Style/RedundantStructKeywordInit	Checks for redundant keyword_init: true.	Enable	Cleans up redundant configuration in modern Ruby where this might be the default or unnecessary.	#13501
Style/SelectByKind	Suggests grep instead of select with type check.	Enable	Encourages use of grep, which is a powerful and idiomatic Ruby feature for type-based filtering.	#14808
Style/SelectByRange	Suggests range slicing instead of select.	Enable	Promotes more concise and performant range-based collection access.	#14810
Style/TallyMethod	Enforces Enumerable#tally.	Enable	Encourages modern Ruby features (tally) for a very common pattern.	#14922

Changed cops

These existing cops had behavioral changes:

Cop	Change	PR
Style/OneClassPerFile	Now excludes spec/**/* and test/**/* by default.	#15005
Style/RedundantStructKeywordInit	Disabled by default.	#15063
Lint/RedundantSafeNavigation	Now aware of safe navigation in conditional true branch.	#14989
Style/HashAsLastArrayItem	Tweaked multiline autocorrection.	#14872
Style/EndlessMethod	Now considers receivers.	#14917
Style/EmptyClassDefinition	Renamed class_definition to class_keyword in EnforcedStyle.	#14895
Style/RedundantInterpolationUnfreeze	Added support for String.new with interpolated strings.	#14956
Style/RedundantParentheses	Now registers redundant parentheses around block bodies.	#14955

The config/ YAML files have not been updated for any of the above cops.
Tests are expected to fail until those configurations are added in a follow-up.
