Overview

This PR implements the interactive Toolbox domain engines in //core/toolbox, powering Calque's sandboxes and universal Omni-Bar.

Components Implemented

1. Toolbox Domain Models (//core/toolbox:ToolboxModels.kt):
   • OmniBar results (OmniBarResult: Number, SuffixRule, FalseCognate, Clitic, WordLookup, None).
   • Trap quiz models (TrapFilter, TrapQuizQuestion).
   • Suffix rule transformation models (TransformedCognateWord).
   • Verb timeline models (ReadingTense, SubjectPronoun, ConjugatedVerbForm, ShiftedSentenceResult).
   • Number/Date/Clock models (NumberAgreementResult, ClockTimeResult, DatePhraseResult).
   • Pronoun surgery models (PronounBlock, PronounBlockType, CliticSurgeryResult).
2. Trap Detector Engine (TrapDetectorEngine.kt):
   • Filtering false cognates by severity/seen status and generating 2-choice disambiguation quizzes.
3. Word Transformer Engine (WordTransformerEngine.kt):
   • Latin cognate suffix morpher (-tion -> -ción, -ty -> -dad, etc.) with Spanish orthographic adjustments (simplifying double consonants).
4. Tense Shifter Engine (TenseShifterEngine.kt, VerbConjugationTables.kt, IrregularConjugationData.kt):
   • Verb timeline engine across 4 reading tenses (Pretérito, Imperfecto, Presente, Ir a + Infinitivo) for regular and irregular verbs.
5. Number Odometer Engine (NumberOdometerEngine.kt):
   • Number counting with gender agreement (apocope un vs una, doscientos vs doscientas), clock time, and calendar dates.
6. Clitic Surgery Engine (CliticSurgeryEngine.kt):
   • Interactive pronoun deconstruction and proclitic/enclitic equivalence builder.
7. Smart Omni-Bar Engine (OmniBarEngine.kt):
   • Query dispatcher routing search strings to numbers/times, cognate suffix rules, false cognates, clitic surgery, or dictionary lookups.
8. Unit Tests:
   • 6 comprehensive test suites covering all sandbox engines and routing scenarios.
