Replaces the four-line stub with a usable landing page: install line,
end-to-end PHP example showing how a caller goes from a log file to
analysed insights, sample (placeholder-laden) output, a one-diagram
architecture summary, and a per-game support table. Sends interested
readers to CLAUDE.md for the extension guide and developer setup so
this file stays focused on consumers.
The example uses Project Zomboid because that is the in-tree reference
implementation. Output is illustrated with placeholder identifiers
(<hash>, <mod_id>, <missing>) rather than copied real-log content.
