b177fa7556 fix: replace mutable default arguments with None + in-body defaults (#1068)
* fix mutable default argument in graph_analyzer.py

* fix mutable default argument in kg_chunkers.py

* fix mutable default argument in methods.py

* Address review: move default-init code out of docstrings, default levels in split_hierarchical

Three findings from the Qodo review:

- analyze_temporal_evolution: the 'if metrics is None' block had landed
  inside the docstring, so it never executed and metrics_tracked came back
  None. Moved below the docstring where it runs.

- HierarchicalChunker.__init__: the same misplacement turned the docstring
  into a dead string constant and broke help()/introspection. Moved the
  default-init below it.

- split_hierarchical: the signature now defaults levels to None, but the
  body still ran 'in levels' membership tests — calling it without levels
  raised TypeError. Defaults to the documented hierarchy, matching the
  class-level default.

* test: add mutable-default regression tests for the three fixed sites

- tests/split/test_chunkers.py: TestMutableDefaultRegression (6 tests)
  - split_hierarchical() default levels and chunk_sizes stay independent across calls
  - HierarchicalChunker() default levels stay independent across instances

- tests/kg/test_kg.py: TestAnalyzeTemporalEvolutionMutableDefault (5 tests)
  - analyze_temporal_evolution() default metrics value is canonical
  - mutations to a returned metrics_tracked list do not affect the next call
  - explicit metrics override is forwarded and reflected in the return value
  - mutating an explicitly passed list does not corrupt a subsequent default call

All 96 tests in the two affected test files pass.
