Port garak's packagehallucination probe into PyRIT as a scenario plus a deterministic scorer, following the web_injection precedent. - Add PackageHallucinationScorer under score/true_false/regex/ (extract-then- allow-list; documented why it does not subclass RegexScorer). - Add PackageHallucination scenario covering Python/JavaScript/Ruby/Rust. - Move the prompt/task corpus into local .prompt datasets under seed_datasets/local/garak/ instead of hardcoding it in scenario code. - Document the scorer in doc/code/scoring/1_true_false_scorers and the scenario in doc/scanner/garak.

…ge-hallucination Migrated the PackageHallucination scenario to main's ScenarioTechnique API (ScenarioStrategy -> ScenarioTechnique, SeedAttackGroup -> AttackSeedGroup) and resolved doc conflicts (added a Doctor section from main, regenerated the true/false scorer notebook to include both the new PackageHallucinationScorer subsection and main's new scorer sections).

Description
Ports garak's
packagehallucinationprobe into PyRIT as a scenario plus a deterministic scorer, following theweb_injectionprecedent.PackageHallucinationScorer(underpyrit/score/true_false/regex/): extracts imported package names from model-generated code and flags any that are absent from an injected known-good reference set (Python stdlib added automatically). It lives beside theRegexScorerfamily but deliberately does not subclass it — its contract is extract-then-allow-list, the inverse ofRegexScorer's match-means-hit — and the docstring explains why.PackageHallucinationscenario covering Python, JavaScript, Ruby, and Rust..promptdatasets underseed_datasets/local/garak/(auto-discovered) rather than being hardcoded in scenario code, keeping dataset ownership out of the scenario.Tests and Documentation
