Updates the dataset card and docs to match the current annotation schema (the
cascade_av devkit, schema_version 2.0.0 incl. the 0.6.x in-place additions).

• License name corrected to NVIDIA Autonomous Vehicle Dataset License
  Agreement (YAML license_name, gated text).
• Record count reconciled to 1,000 throughout (with the 1,000 seeds ->
  ~30,000 candidates -> 1,000 annotated selection funnel).
• eventful_reason clip-level field documented (ego_adapts /
  special_environment / agent_adapts / other).
• Action flags vs. properties corrected: the only action-level flag is
  illegal; erratic/aggressive/stopped/etc. are agent/ego properties.
  jaywalking is the standalone Jaywalk action.
• link_to removed from the narrative (effectively unused: only
  SignalingDetails.link_to, ~8/300 clips); kept as a minimal field entry in
  schema.md. because_of / action_target / influenced_by are the
  interaction relations.
• influenced_by documented as a first-class relation/operator.
• Environments & containment documented as optional (sparse-to-absent
  depending on annotation scope; the "dense" overclaim dropped).
• New vocab: Stopped, Jaywalk, fst:SpeedBump / fst:LightRailLane,
  Left/Right Indicator, Boom gate; agent amount Single / Row-group.
• DevKit URL updated to https://github.com/nv-tlabs/cascade-devkit.
