feat(taskserv): implement real-time version checking with configurable HTTP client

- Add: GitHub API integration for live version checking in taskserv management
- Add: HTTP client configuration option (http.use_curl) in config.defaults.toml
- Add: Helper function fetch_latest_version with curl/http get support
- Fix: Settings path structure for prov_data_dirpath access pattern
- Remove: Legacy simulation code for version checking
- Update: Core configuration name from "provisioning-system" to "provisioning"
- Clean: Remove obsolete example configs and infrastructure files
