Make CLI command discovery closer to Claw Code

Improve top-level help and shared slash-command help so the implemented surface is easier to discover, with explicit resume-safe markings and concrete examples for saved-session workflows. This keeps the command registry authoritative while making the CLI feel less skeletal and more like a real operator-facing tool.

Constraint: Help text must reflect the actual implemented surface without advertising unsupported offline/runtime behavior
Rejected: Separate bespoke help tables for REPL and --resume | would drift from the shared command registry
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Add new slash commands to the shared registry first so help and resume capability stay synchronized
Tested: cargo fmt --manifest-path ./rust/Cargo.toml --all; cargo clippy --manifest-path ./rust/Cargo.toml --workspace --all-targets -- -D warnings; cargo test --manifest-path ./rust/Cargo.toml --workspace
Not-tested: Manual UX comparison against upstream Claw Code help output
