Parliamentary AI Coverage Tracker
===================================
Analyses how often UK Members of Parliament mention AI, superintelligence,
and related terms in Hansard parliamentary debates using the official
Parliament API.

Tracks:
  - Frequency of AI mentions over time
  - Which MPs mention AI most frequently
  - Which topics cluster around AI mentions
  - Trend analysis: is AI discourse accelerating?

Directly mirrors ControlAI's UK legislative engagement work —
they have briefed 150+ parliamentarians since September 2024.
