copilot-swe-agent[bot]andRyanCavanaugh 869eb505d5 Fix contextual typing sensitivity to binding pattern structure

copilot-swe-agent[bot]andRyanCavanaugh 649c90af15 Fix contextual typing sensitivity to binding pattern structure 
Modified getTypeFromArrayBindingPattern to make contextual type construction
agnostic to whether tuple destructuring elements have binding names. When
includePatternInType is true, cap minLength at 2 to ensure consistent
contextual types regardless of binding pattern variations.

This fixes an issue where [, , t] and [, s, ] produced different contextual
types, causing inconsistent generic type inference and spurious excess
property errors.

Addresses feedback in #41548 about making contextual types position-agnostic.

copilot-swe-agent[bot]andRyanCavanaugh 4235412daa Detailed investigation of tuple destructuring excess property issue 
Reverted all previous changes and conducted thorough analysis of the root cause.
Found that the issue is related to contextual typing and generic type inference,
not specifically the "last element position" but rather the pattern of
first element omitted + last element named.
