refactor(scripts): update scripts for new experiment framework

Update scripts to work with the new metrics pipeline:

- generate-latex-tables.ts: Refactored to read MetricsOutput format
  from run-experiments.ts instead of parsing test output. Simplified
  table generation with new MetricsOutput interface.

- run-tap.ts: Added algorithm comparison parsing for the new
  evaluation harness output. Updates "Path Salience vs Random"
  test to use "MI" instead of "diversity" metric.

This removes the fragile console-output parsing dependency from
the LaTeX generation pipeline.
