Improve CLI outputs for agentic use (incl. lower token consumption)

[Camil-H]

Problem

There are a few issues with the current CLI when used by agents.

Feature

• Stdin/pipe input support
  → Support reading input from stdin or --from-file to enable composable pipelines between tools.
• Add Help text with usage examples
  → Include an Examples section in --help output so agents can learn correct usage patterns.
• Add a --no-color flag, for lower token consumption
• Add a --quiet / --silent flag, for lower token consumption
• Add a --concise / --short flag, for lower token consumption
