Tidesman v0.1.1

Post-launch hardening release.

• Added --help, --version, and -h.
• More accurate engine-down detection: Tidesman now corroborates whether the container engine is actually running before telling you to start it, so a normal command failure is no longer mislabeled as "the engine isn't responding."
• container_kill is now idempotent on an already-stopped container, and its result reports honestly whether a signal was delivered.
• A misspelled or unknown image now reports as a bad image name rather than a raw registry authorization error.
• system_ping reports the active access mode (read-only / safe / full).
• Clearer, better-targeted error messages for delete and run failures.
• Non-zero exit codes on launch and configuration errors.
