/**
 * Tour command — author, validate, analyze, and open File City introduction
 * tours (`*.tour.json`).
 *
 * Tours are the sibling of trails: a trail pins markers to `file:line`, a tour
 * scopes steps to a `focusDirectory` + highlight layers. This command bundles
 * the full tour lifecycle:
 *
 *   principal-ai tour init      scaffold a tour from a template
 *   principal-ai tour validate  validate a tour against the spec
 *   principal-ai tour stats      timing/length analysis vs. the guidelines
 *   principal-ai tour view      open a tour in the standalone viewer
 *
 * `init`/`validate`/`stats` were folded in from the deprecated
 * `@principal-ai/file-city-cli`; they delegate all schema work to
 * `@principal-ai/file-city-builder` (`parseTour`, `IntroductionTour`). `view`
 * is the lighter cousin of `trail view --file`, reusing the same viewer-launch
 * + IPC handoff plumbing — and because steps address whole directories, tours
 * are local-mode only (no fetch, no remote slice resolution, no token).
