Users currently need to scan a flat help list, interpret raw operation states, and manually reconstruct commands after errors. This change makes existing commands easier to navigate and their results easier to act on, while preserving explicit JSON/YAML output for agents.

• Group help by purpose, show applicable/required options and common examples, and complete saved contexts and static enums offline.
• Show the selected configuration and credential availability; allow context show without a name and provide next-step commands that retain connection options.
• Put resource names and status first, preserve full IDs, handle narrow terminals, and add client-side name/ID filtering with --filter.
• Clarify preflight, submitted/completed tasks and partial verification; add terminal-only waiting feedback and an offline schema --summary index with command-group lookup.

The change updates 12 existing files, adds no source files or dependencies, and increases the stripped Windows binary by 71.5 KiB (0.65%). English and Chinese READMEs describe the resulting behavior. Local before/after review material is excluded.

Validation

• go test ./... and go vet ./... passed on the current implementation.
• Exercised the CLI against the existing Docker-hosted Core v4.10.11 instance: all nine resource lists retained identical JSON data without filtering; checked filtering, Bot update dry-run, completion and context operations using a temporary configuration.
• Replayed submitted/completed tasks, hidden-field verification and long-name output through the actual renderers without changing live resources.
• git diff --check passed.
