Add ASR reporting by converter type

[Copilot]

Adds converter type grouping to attack result analytics. Enables comparing effectiveness of different converters (Base64, ROT13, translation, etc.) across attacks.

Changes

• pyrit/analytics/result_analysis.py: Extended analyze_results() to extract converter class names from AttackResult.last_response.converter_identifiers and compute stats per converter type. Returns new "By_converter_type" dict alongside existing groupings.

• tests/unit/analytics/test_result_analysis.py: Added 5 tests covering no-converter tracking, single/multiple converters per attack, and undetermined outcomes. Added make_converter() helper to reduce duplication.

Behavior

Attacks without converters tracked as "no_converter". Pipeline attacks with multiple converters contribute to each converter's stats independently.

results = analyze_results(attack_results)

# New grouping available
results["By_converter_type"]["Base64Converter"]
# AttackStats(success_rate=0.75, successes=3, failures=1, undetermined=0, total_decided=4)

Non-breaking change - preserves existing return structure.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• astral.sh
  • Triggering command: /usr/bin/curl curl -LsSf REDACTED (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

we have so many things to filter on, I'm wondering if we want to go this route or something more general. E.g. filtering on any ConverterIdentifier field
