[compiler] Phase 4 (batch 2), 5, 6: Update remaining passes for fault tolerance

Update remaining validation passes to record errors on env:
- validateMemoizedEffectDependencies
- validatePreservedManualMemoization
- validateSourceLocations (added env parameter)
- validateContextVariableLValues (changed throwTodo to recordError)
- validateLocalsNotReassignedAfterRender (changed throw to recordError)
- validateNoDerivedComputationsInEffects (changed throw to recordError)

Update inference passes:
- inferMutationAliasingEffects: return void, errors on env
- inferMutationAliasingRanges: return Array<AliasingEffect> directly, errors on env

Update codegen:
- codegenFunction: return CodegenFunction directly, errors on env
- codegenReactiveFunction: same pattern

Update Pipeline.ts to call all passes directly without tryRecord/unwrap.
Also update AnalyseFunctions.ts which called inferMutationAliasingRanges.
