v1.0.0

Added

• Core snapshot slice: YAML config with env-var-only camera passwords, a
  CameraManager connection layer, and the list_cameras and get_snapshot
  tools — a live, unconditionally downscaled snapshot from a real camera
  through an MCP client, session-safe alongside other systems on the same
  hardware.
• Full observe surface: get_device_info, get_capabilities, get_states,
  and get_recent_events — model/firmware details, capability discovery,
  live device state, and on-demand AI detection polling, validated on the
  P437 and P320.
• Safe controls and safety rails: nine control tools (set_siren,
  set_audio_alarm, set_spotlight, set_ir_lights, set_white_led,
  set_zoom, list_presets, ptz_move_to_preset, ptz_position,
  ptz_guard), capability gating on every control, RMCP_READ_ONLY mode,
  and MCP tool annotations (readOnlyHint/destructiveHint) so clients can
  gate approvals on observe vs. control.
• Packaging and release: PyPI publish metadata, an MCP Registry manifest
  (server.json), and a hardware-free CI pipeline (ruff + pytest across a
  3.11/3.12/3.13 x ubuntu/macos/windows matrix, plus a per-OS packaging
  smoke check).
