When running in CI environments, interactive prompts can hang indefinitely because some CI systems allocate pseudo-TTYs. This change adds automatic CI detection that disables interactive mode and provides helpful error messages guiding users to use non-interactive flags. - Add centralized `environment` module with `is_interactive()` and `non_interactive_reason()` functions - Detect CI via environment variables: CI, GITHUB_ACTIONS, GITLAB_CI, CIRCLECI, TRAVIS, JENKINS_URL, BUILDKITE, TF_BUILD - Add CARGO_CHANGESET_NO_TTY to explicitly disable interactive mode - CI detection takes priority over CARGO_CHANGESET_FORCE_TTY - Consolidate duplicate `is_interactive()` functions from interaction.rs, commands/add.rs, and commands/manage.rs - Enhance error messages to show which CI env var was detected and provide guidance on required flags - Add integration tests for CI detection behavior - Document CI usage in README with examples
FORCE_TTY is an explicit override that allows interactive mode even in CI, so it must take precedence over CI env var detection. This fixes interactive tests running in GitHub Actions where CI=true caused the binary to exit non-interactively despite FORCE_TTY=1 being set. Also fixes add_in_non_tty_multi_crate_workspace_fails to clear all CI env vars so it reliably tests the NoTerminal code path rather than CI detection.
