agent refactoring (#27)

* feat(context): restructure context module by creating a dedicated context directory and moving related functions to improve organization and maintainability
refactor(agent): simplify agent logic by modularizing action execution and communication functions for better readability and separation of concerns
chore: remove unused utils directory and update imports across the codebase to reflect new structure

* refactor(agent): reorganize action and error types into separate files for better modularity and maintainability
chore(agent): remove deprecated types.ts file to clean up the codebase and avoid redundancy
