feat(core): export complete type system from core module

Add comprehensive exports for all types, models, and protocols from
the core module, making them easily accessible to other parts of
the framework.

Exports:
- Semantic types and factory functions
- All configuration models (actions, options, branches, wizard)
- All protocols (ActionExecutor, OptionCollector, NavigationController)
- Result types
- Type guards and collection aliases

Part of CLI-4: Minimal Core Type Definitions

+"""Core types and protocols for CLI Patterns.
+
+This module provides the foundational type system for the CLI Patterns framework:
+
+Types:
+    - Semantic types: BranchId, ActionId, OptionKey, MenuId
+    - State value types: StateValue (JSON-serializable)
+    - Type guards and factory functions
+
+Models:
+    - Configuration models: WizardConfig, BranchConfig, MenuConfig
+    - Action models: BashActionConfig, PythonActionConfig
+    - Option models: StringOptionConfig, SelectOptionConfig, etc.
+    - State models: SessionState
+    - Result models: ActionResult, CollectionResult, NavigationResult
+
+Protocols:
+    - ActionExecutor: For executing actions
+    - OptionCollector: For collecting option values
+    - NavigationController: For navigation control
