[grandizzy]

Motivation

Closes #4393

Solution

• exit with command failed only on failures: show traces and failed are handled in same branch
  

  foundry/crates/chisel/src/dispatcher.rs

  Line 704 in 2044fae

  if new_session_source.config.traces || failed {

  
  and both results now in command failed as failed bool is not checked

  	// If the contract execution failed, continue on without
  	// updating the source.
  	DispatchResult::CommandFailed(Self::make_error(
  	"Failed to execute edited contract!",
  	))
