feat(WP-0003c): context adapters, first ActivityDefinition, full test suite
T51: ContextResolver ABC + CONTEXT_RESOLVER_REGISTRY; resolve_context activity
updated to dispatch via registry (warns + binds {} on failure, never aborts run).
T52: RepoScopingContextResolver with 5-min in-process cache.
T53: StateHubContextResolver (no cache) for domain_summary and repo_sbom_status.
T54: activity-definitions/weekly-sbom-staleness.md (Monday 09:00 Berlin, cron
trigger, flag-stale-sbom rule at >30 days) + tasks/sbom-rescan.md template.
T55: 51 parametrized evaluator tests — all whitelisted operators, unsafe
expression rejection, empty condition, missing attribute, nested context access.
T56: 15 executor safety tests — UntrustedFieldError, object-type rejection,
injection fixture, LLM retry on bad JSON, review_required field.
T57: 6 integration tests — parses real definition, evaluates rule per-repo
(stale/fresh boundary), emits via NullSink, verifies spawn log entries.
