Synchup with Agent Framework

[alexheifetz]

This pull request refactors how feedback and evaluation results are accessed within the repeat-until loops in both GoatWriterConfig.java and ReviseStoryUntilSatisfied.java. The main improvement is switching from retrieving feedback and evaluation results via context.getInput() to using more direct methods on the context object, which simplifies the code and makes it clearer.

Refactoring feedback and evaluation retrieval:

• Updated feedback retrieval in both goatWriter() and rewriteUntilSatisfied() methods to use context.lastAttempt() instead of context.getInput().lastFeedback(), improving clarity and directness. [1] [2]
• Changed result evaluation access to use context.getResultToEvaluate() rather than context.getInput().resultToEvaluate(), streamlining how the result to be evaluated is obtained. [1] [2]

Code cleanup:

• Removed an unnecessary import in GoatWriterConfig.java for tidier code.
