• Resolve class-local names in generic type aliases (#29915)

LSP server

• Respect FORCE_COLOR in ty check even when output is piped (#29830)

Diagnostic improvements

• Reuse inferred annotations when checking function returns (#29879)
• Reuse inherited override checks across subclasses (#29867)
• Reuse parameter unions when filtering overloads (#29823)
• Short-circuit equivalence checks against Never (#29862)
• Skip generic call inference when only a concrete receiver's Self needs binding (#29747)
