Summary

Implement the router-facing create_executor() factory function and Executor class with async execute() method returning ActorResult.

What This PR Does

Production Code

• src/cleveractors/runtime.py — create_executor() factory, Executor class, ActorResult/NodeUsage dataclasses (~183 lines)
• src/cleveractors/runtime_dispatch.py — Four dispatch methods: _execute_llm, _execute_graph, _execute_tool, _execute_multi_actor (~420 lines)
• src/cleveractors/runtime_tokens.py — Token estimation via tiktoken with heuristic fallback, lru_cache on encoding lookup, _Encoding Protocol for return typing
• Credential injection via AgentFactory(credentials=...) — stored config_dict never modified (ADR-2026 AC8)
• Mutable state hygiene: _usage_log.clear() at start of execute() for AC5 compliance; direct assertion in tests
• Config immutability: copy.deepcopy() used in both _execute_graph and _execute_multi_actor
• File size compliance: Both runtime modules under 500 lines (CONTRIBUTING.md)
• Cleanup logging at WARNING level for agent cleanup failures

Code Review Fixes (Cycle 6)

ID	Priority	Fix
message validation	MAJOR	Added isinstance(message, str) guard at top of Executor.execute() with BDD scenario in credential_executor_validation.feature
step_execute_actor guard	MAJOR	Changed context.credentials direct access to getattr(context, "credentials", None) for consistency with limits/pricing guards
empty nodes_cfg BDD	MAJOR	Added BDD scenario in runtime_coverage.feature for _execute_graph with route.nodes = []
config reference doc	MINOR	Added comment documenting config_dict reference-storage assumption in Executor.__init__
deepcopy sub_config	MINOR	Changed sub_config.copy() to copy.deepcopy(sub_config) in _execute_multi_actor for nested-dict safety
credentials=None BDD	MINOR	Added BDD scenario for create_executor(credentials=None) standalone mode
lru_cache isolation	MINOR	Added _get_encoding.cache_clear() to environment.py before_scenario for defensive test isolation
_TIKTOKEN_AVAILABLE doc	MINOR	Added module-level comment documenting import-time-only assumption in runtime_tokens.py
n9	NIT	Removed redundant quoted forward references in runtime_dispatch.py (PEP 563 makes them unnecessary)
n10	NIT	Parenthesized and split long edge-validation condition in _execute_graph
n11	NIT	Updated AC7/AC8 comment to AC7 only in _execute_graph
n12	NIT	Added belt-and-suspenders comment in credential_graph_cleanup_steps.py finally block explaining dual cleanup rationale

feat(create_executor): implement create_executor() factory and Executor.execute() returning ActorResult ... 05cb9beb04

The implementation was already completed as part of #12's credential injection
work (commit f281fa3). This commit completes the ticket by adding the missing
BDD test coverage and bringing overall coverage from 96.68% to 97.03%,
meeting the >=97% project threshold.

## What was already done (f281fa3, e7a7d39)

- Executor class wrapping PureLangGraph and AgentFactory (runtime.py)
- create_executor() factory function accepting config_dict, credentials,
  limits, pricing
- _execute_llm() uses AgentFactory(credentials=...) — never constructs
  LLMAgent directly
- _execute_graph() uses AgentFactory(credentials=...) — no _build_factory_config()
  credential-mutation path
- _execute_tool() and _execute_multi_actor() dispatch paths
- export from cleveractors/__init__.py and __all__

## Coverage improvements added in this commit

### runtime.py (0 missing lines, 100% coverage)

- credential_injection.feature: new scenario "_execute_llm falls back to
  config block when top-level fields absent" exercises Executor._execute_llm()
  with config values stored inside a nested config: block rather than at the
  top level (runtime.py lines 164, 167, 170, 174, 178).
- credential_injection.feature: new scenario "_execute_graph wraps generic
  Exception from create_agent in ConfigurationError" exercises the
  except Exception handler in _execute_graph() (runtime.py lines 333-341).

### runtime_tokens.py (only 3 lines missing — module-level ImportError block)

- runtime_coverage.feature: new scenario with model="llama-3-70b" hits the
  cl100k_base fallback path (line 41).
- runtime_coverage.feature: new scenario patches tiktoken.get_encoding to
  raise, exercising the except Exception fallback (lines 45-50).
- runtime_coverage.feature: new scenarios for estimate_graph_tokens() with
  tiktoken available (lines 62-65), tiktoken raising (lines 66-70), and
  tiktoken unavailable (lines 73-74).

### agents/factory.py (2 lines remaining — factory.py lines 277-278)

- credential_injection.feature: new scenarios for AgentFactory constructor
  with non-dict config and non-TemplateRenderer (factory.py lines 87-93).
- credential_injection.feature: new scenarios for validate_credentials_structure
  with non-dict-non-None credentials via AgentFactory (llm_providers.py lines
  90-91) and non-str inner key (llm_providers.py lines 108-110).

## Quality gates

All quality gates pass: lint, typecheck, unit_tests (2038 scenarios),
integration_tests (76 tests), coverage_report (97.03%), security_scan,
dead_code.
