[compiler] Fix Pipeline.ts early-exit, formatting, and style issues

Fix the transformFire early-exit in Pipeline.ts to only trigger on new
errors from transformFire itself, not pre-existing errors from earlier
passes. The previous `env.hasErrors()` check was too broad — it would
early-exit on validation errors that existed before transformFire ran.

Also add missing blank line in CodegenReactiveFunction.ts Context class,
and fix formatting in ValidateMemoizedEffectDependencies.ts.
