test: add coverage gap tests improving coverage from 81.4% to 96.90%
Add 13 BDD scenarios covering previously uncovered code paths:
- SAFE_BUILTINS validation (sandbox.py: 0% → 100%)
- ConfigurationError re-raise path (config.py: 99.3% → 100%)
- CLI hello/main functions (cli.py: 72.7% → 90.9%)
- GraphState message truncation (state.py: 98.7% → 100%)
- ProgressBarManager update/context rendering (progress.py: 0% → 87.7%)
- MessageRouter regex/exact/contains routing (message_router.py: 0% → 59.4%)
- RoutingAdapter parse_routing_command (routing_adapter.py)
- DynamicRouterNode pattern-based routing (dynamic_router.py)
- EnhancedTemplateRegistry unknown template type (enhanced_registry.py: 99.2%)
- CompositeAgent null-graph error path (composite.py: 97.8% → 98.6%)

Cover routing_adapter.py (17% → 100%): all GOTO/ROUTE patterns,
create_routing_node, create_conditional_router, dynamic config conversion.

Cover dynamic_router.py (21% → 87%): execute with empty/dict/string
messages, extract_message with colon parsing, config creation, graph
extension with edge generation.

Cover message_router.py (59% → 78%): regex, exact, contains, prefix,
suffix match types, invalid regex handling, non-string message, set_state.

Exercise Node._prepare_conversation_history with invalid configs,
_runtime error paths, _execute_message_router with rules,
_execute_agent with current_message and metadata propagation,
_execute_function with dynamic_router, and _execute_conditional
with content_contains/content_not_contains/content_starts_with
and custom condition types. Improves nodes.py from 71.3% to 72.5%.

Exercise PureGraphConfig, PureLangGraph init with dict/config,
RxPyLangGraphBridge registration/connection/lookup,
ReactiveStreamRouter operator creation and condition functions,
ReactiveConfigParser config/route/graph parsing,
ToolAgent tool execution with JSON, space-separated, single,
file_read, progress_bar invocations, and
ReactiveCleverAgentsApp init/dispose/visualization.

Feature: LangGraph Node Initialization, Execution, and Error Handling
As a CleverAgents developer
I want nodes to initialize correctly, execute across all node types, and handle errors with retries
So that graph execution is reliable for agent, function, conditional, subgraph, and tool nodes
Background:
Given the LangGraph nodes system is initialized
Scenario: Node initialization and core execution paths
Given I have various node configurations
When I test node initialization and basic execution
Then all node types should initialize correctly
And basic execution should work for each type
Scenario: Agent node execution scenarios
Given I have various node configurations
When I test agent node execution paths
Then agent execution should handle valid agents correctly
And error cases should be handled properly
Scenario: Function node execution scenarios
Given I have various node configurations
When I test function node execution paths
Then all built-in functions should execute correctly
And unknown functions should return empty results
Scenario: Conditional node execution scenarios
Given I have various node configurations
And I have conditional node test configurations
When I test conditional logic execution
Then all condition types should evaluate correctly
And conditional edge cases should be handled properly
Scenario: Node utility methods and properties
Given I have various node configurations
When I test node utility methods
Then timeout and parallel settings should work
And edge operations should function correctly
Scenario: Error handling and retry mechanisms
Given I have various node configurations
When I test error handling scenarios
Then errors should be captured and returned properly
And retry policies should work without delays
