"""
intent_interview.py -- New-repo / existing-repo intent interview.

The "fresh-repo-init" toolbox exists so that an unfamiliar repo can bootstrap
its toolbox set without a human designing one from scratch. This module is
the brain behind that toolbox:

  1. Inspect repo state (git? commits? languages? existing toolbox config?).
  2. Build a structured question list from that state (plus any behaviour
     profile already on disk).
  3. Accept answers either interactively (stdin) or structurally (--accept
     key=value pairs, or --preset for a canned flow).
  4. Return an InterviewResult that a caller can apply to the global
     ToolboxSet via ``apply_result`` -- writes are explicit and atomic.

Design choices:
- *Three* answer paths per spec: interactive, structured (non-interactive),
  or skip entirely. No UI framework \u2014 plain stdin, plain argparse.
- The module produces an InterviewResult; it does not mutate global config
  unless ``apply_result`` is called explicitly. This keeps dry-runs safe.
- Suggestions come from the persisted BehaviorProfile (if any). The
  interviewer *surfaces* them but never auto-accepts \u2014 the user chooses.
- Starter templates are discovered via the existing toolbox.py loader so
  there is exactly one source of truth for what "fresh-repo-init" offers.

CLI:
  python intent_interview.py detect                   # print RepoState
  python intent_interview.py init                     # interactive flow
  python intent_interview.py init --non-interactive \\
      --starters ship-it,security-sweep \\
      --suggestions 1,3                               # pre-answered flow
  python intent_interview.py init --skip              # skip, write nothing
  python intent_interview.py init --preset blank      # auto blank-repo preset
  python intent_interview.py init --preset existing   # auto existing-repo preset
