release: v0.2.0

Comprehensive release containing structural, UX, and behavioral upgrades since v0.1.0:

1. Namespace Transition: Renamed core executable and project namespaces from 'smart-monitor' to 'smart-shutdown'.
2. Objective Vocabulary Refactoring: Normalized output strings and logging descriptors system-wide to a strict, professional tone.
3. Advanced Status Query: 'status' subcommand now retrieves the parsed configuration, log locations/sizes, and tails the last 10 lines of the local log file.
4. Runtime Configuration Setter: Introduced 'config set' subcommand to modify the configuration file with strict type validations.
5. Auto-System Deployment: Remapped 'install' to clone the executable into system domains and register global PATH variables.
6. Cleaner Removal: 'uninstall' purges binary clones and clears environmental variables, leaving zero traces.
7. Documentation Rewrite: Generated an objective README file featuring copy-paste ready Markdown blocks.
