Description

• Annotate SeedIdentifier.from_seed with Self.
• Add base/subclass runtime and assert_type regression coverage.
• P311-01: SeedIdentifier.from_seed. Relates to Python 3.11 adoption opportunities: claim one improvement at a time #3166; this focused change does not complete the whole tracker.
• Runtime factory behavior, behavioral parameter projection, hashes, and serialization are unchanged.

What changed in this PR

This PR extends Python 3.11 Self adoption to SeedIdentifier.from_seed, preserving concrete subclass types in static typing without changing runtime behavior.

Changes:

• Annotates the factory return type with Self.
• Adds base/subclass regression coverage using assert_type and runtime type assertions.

File	Description
tests/​unit/​models/​identifiers/​test_atomic_attack_identifier.py	Adds static and runtime checks for base and subclass factory results.
pyrit/​models/​identifiers/​seed_identifier.py	Imports Self and updates the factory return annotation.
