/**
 * `aidlc update` command — update the CLI and refresh project skills.
 *
 * Behavior:
 * 1. Self-update: detect the package manager that installed AIDLC globally,
 *    check the npm registry for the latest version, and update if needed.
 * 2. Project refresh: if inside a project with `.aidlc/config.yaml`, re-run
 *    `init` for each configured platform to refresh skill shims and steering.
 * 3. Optionally re-run discovery to regenerate context docs (--rediscover).
 *
 * Options:
 *   --self-only       Only update the CLI, skip project refresh
 *   --project-only    Only refresh project files from the current CLI
 *   --rediscover      Also regenerate context docs (.aidlc/context/)
 *   --dry-run         Show what would change without writing
 *
 * Requirements: 17.1
 *

/**
 * Print what the refresh changed, in enough detail to judge whether prose died.
 *
 * The old output was one `+` per path, with `+` used for create and for
 * overwrite-with-loss alike, no legend, and no counts. A careful operator who
 * dry-ran first still could not see that text was about to be deleted — which is
 * the whole defect this instance was filed for. Three things changed:
 *
 * - `new` and `~` distinguish a created file from a replaced one (AC-3).
 * - `+N/-M` gives the size of the replacement (AC-3). Whole-file counts, not a
 *   diff stat, which is why the legend says so (R4).
 * - a legend precedes the list, because a marker nobody can look up is not a
 *   signal (AC-3).
 *
 * Exported for the tests, which assert on the rendered lines rather than
 * re-deriving them.
