feat: add advanced CLI completion, validation, and config for robust SCP-like transfers (#3)

**Key Changes:**

- Added shell completion for buckets, instance IDs, and remote paths
- Implemented comprehensive input validation for source, SSM path, and bucket
- Introduced YAML-based configuration with logging and transfer tuning
- Added robust logging, error handling, and retry logic to file transfers
- Closes #1 
- Closes #2

**Added:**

- Shell completion commands (`completion [bash|zsh|fish|powershell]`) and context-aware argument completion for buckets and SSM instances (`cmd/completion.go`, `pkg/completion/aws.go`)
- `list` command to enumerate S3 buckets and EC2/SSM instances, with region and filtering options (`cmd/list.go`)
- YAML config support with example (`cmd/config/config.yaml`, `pkg/config/config.go`), including logging, AWS, and transfer sections
- Structured logging package (`pkg/logging/logging.go`) with JSON/text formats and log level control
- Input validation utilities for source path, SSM path, and bucket names (`pkg/validation/input.go`)
- Retry and exponential backoff for S3/SSM transfers in `pkg/transfer/transfer.go`
- Taskfile for build/test/dev automation (`Taskfile.yaml`)
- Pre-commit hooks for formatting, linting, licenses, and vulnerability checks (`.pre-commit-config.yaml`, `.hooks/*`)
- Extensive unit tests for all new components

**Changed:**

- Main command (`cmd/root.go`) refactored to use new config, validation, logging, and transfer logic
- Improved argument parsing, error messages, and user feedback in CLI
- Updated `.gitignore` to reflect modern Go and project artifacts
- README fully rewritten to document new features, usage, shell completions, and troubleshooting

**Removed:**

- Legacy or redundant pre-commit scripts (e.g., `.hooks/go-critic.sh`, `.hooks/linters/mdstyle.rb`)
- Deprecated markdownlint Ruby style, replaced with modern JSON configuration
