docs(skill): document sendNotification action (7 actions total) + CLI support

- skill: SKILL.md (7 actions in description + routing table entry), action-types.md

  automation-guide.md/cli-reference.md (--to-user/--title/--message/--severity/--path),

- cli: action add --type sendNotification now builds config from granular flags
  (toUserId/title/message/severity/path); ACTION_TYPES includes sendNotification;

+- `title` + `message`: notification text; both support `{{nodeId.path}}` variables. If title set, rendered as `title\nmessage`.

+- `severity`: `info` (default) | `warning` | `critical`.
