Use new proposed AttributionTargets API for circuit-tracer, misc infra improvements

[speediedan]

This PR updates the circuit-tracer integration to use the new proposed AttributionTargets API, switches basic examples to use CLT by default, improves infrastructure utilities, and includes minor test adjustments for PyTorch 2.9 compatibility. Changes span the circuit_tracer adapter, attribution analysis notebooks, example scripts, version management, and CI requirements.

Pull Request Overview

This PR updates the circuit-tracer dependency to a newer commit and implements package name normalization according to PEP 503 to better handle packages with different naming conventions (hyphens vs underscores).

Key Changes:

• Updates circuit-tracer commit pin from b228bf1... to 004f1b2... across all dependency files and notebooks
• Implements PEP 503 package name normalization in PackageVersionManager to canonicalize package names (converting underscores, dots to hyphens)
• Refactors circuit-tracer API usage to use attribution_targets parameter instead of analysis_target_indices
