Reduce CLI dead-ends around help and session recovery

The Rust CLI now points users toward the right next step when they hit an
unknown slash command or mistype a flag, and it surfaces session shortcuts
more clearly in both help text and the REPL banner. It also lowers session
friction by accepting `latest` as a managed-session shortcut, allowing
`--resume` without an explicit path, and sorting saved sessions with
millisecond precision so the newest session is stable.

Constraint: Keep the change inside the existing Rust CLI surface and avoid overlapping new handlers
Constraint: Full workspace clippy -D warnings is currently blocked by pre-existing runtime warnings outside this change
Rejected: Add new slash commands for session shortcuts | higher overlap with already-landed handler work
Rejected: Treat unknown bare words as invalid subcommands | would break shorthand prompt mode
Confidence: high
Scope-risk: moderate
Directive: Preserve bare-word prompt mode when adjusting CLI parsing; only surface guidance for flag-like inputs and slash commands
Tested: cargo clippy -p rusty-claude-cli --bin claw --no-deps -- -D warnings
Tested: cargo test -p rusty-claude-cli
Tested: cargo run -q -p rusty-claude-cli -- --help
Tested: cargo run -q -p rusty-claude-cli -- --resum
Tested: cargo run -q -p rusty-claude-cli -- /stats
Not-tested: Full workspace clippy -D warnings still fails in unrelated runtime code
