v0.1.1

Fixed

• CLI version flag — the version string passed to Commander was hardcoded as "0.1.0".
  It now uses createRequire(import.meta.url) to load the version field from package.json
  at runtime, so -V always reflects the published package version.
• --count validation (spec 29) — generate --count 0, --count -1, and --count abc
  now exit with code 1 and a clear error message to stderr instead of silently outputting an
  empty array. Numeric values are displayed unquoted; non-numeric strings are quoted.
  Example: Error: --count must be a positive integer, got 0
• --annotate pipeline hint (spec 30) — When --annotate is used and stdout is a TTY
  (interactive terminal), a hint is printed to stderr explaining that piping to
  fhir-resource-diff validate requires extracting .resource first via jq '.resource'.
  The hint is suppressed when stdout is piped — it never appears in pipe output.
  The --annotate help text now documents the { resource, notes } wrapper shape and the
  required jq workaround for pipeline use.
