feat: add commands for managing deployments and resources

- Implemented `down` command to delete managed resources, with an option to delete ingress and PVCs.
- Added `exec` command to execute commands inside deployment pods.
- Created `logs` command to show deployment logs with an option to follow the output.
- Introduced `start` command to start deployments without rebuilding images.
- Developed `stop` command to scale managed deployments to zero.

refactor: enhance resource management and Kubernetes interactions

- Refactored resource handling in `lib/apply.ts` to support sorting and applying resources.
- Improved logging functionality with a new logger in `lib/logger.ts`.
- Enhanced build process in `lib/build.ts` to support remote builds and syncing with Git repositories.
- Added functions to manage deployments and pods in `lib/shared.ts`.

chore: update dependencies and TypeScript configuration

- Updated package.json to include `listr2` for task management.
- Modified tsconfig.json to exclude build artifacts and fixtures.
