feat: Add 'predix evaluate' command to CLI

Integrated predix_full_eval.py into the main Predix CLI.

New command:
  predix evaluate [--top N] [--all] [--parallel P] [--force]

Features:
- Evaluates factors with full 1min data (2020-2026)
- Computes IC, Sharpe, Max DD, Win Rate
- Automatically skips already evaluated factors
- --force flag to re-evaluate all factors
