Incorrect Tranco site count (100M instead of 1M)

[abhizaik]

Description

Project currently references Tranco as containing the top 100 million websites in multiple places (docs, API response).
This is incorrect, the Tranco list only includes the top 1 million websites.

Impact

This may mislead users and reduce project credibility.

Steps to Fix

• Replace all mentions of "100 million" with "1 million" across:

  • Documentation
  • API responses

• Verify consistency throughout the codebase.

Expected Outcome

All references to Tranco correctly state 1 million websites.
