docs(styleguides+harness-plan): fix stale models.py refs + harness plan line drift

Styleguides:
- agent_memory_dimensions.md: FileItem/ContextPreset line refs
  (src/models.py:510-559 / 909-937) -> src/project_files.py +
  src/context_presets.py (moved per module_taxonomy_refactor_20260627).
- config_state_owner.md: 'file I/O primitives in src/models.py' ->
  src/project_manager.py (the config-load/save helpers moved).
- python.md §10 NOT-exempt list: '12 per-aggregate types' -> ~19;
  'dataclass types in src/models.py' -> per-system files enumeration
  (mma.py, project_files.py, mcp_tool_specs.py, result_types.py,
  personas.py, workspace_manager.py, mcp_client.py).
- type_aliases.md: type-registry lookup examples updated to the
  per-system files (src_mma.md, src_project_files.md, etc.); the
  'src/models.py: 48 dataclass field types' worked-example line is
  flagged as historical (pre-refactor state).

Harness plan (directive_hotswap_harness_20260627/plan.md):
- §17 line refs corrected: 17.1 220-237 -> 247-264; 17.2 239-250 ->
  266-277; 17.3 252-272 -> 279-299; 17.4 274-299 -> 301-326; 17.5
  301-311 -> 328-338; 17.6 313-323 -> 340-350; 17.7 325-327 ->
  352-354; 17.9 336-409 -> 364-443.
- §17 master range 216-409 -> 243-473.
- §12 175-184 -> 202-211; §13 185-199 -> 212-224; §15 205-215 ->
  234-241.
- error_handling.md: hard rules 212-242 -> 212-264; boundary types
  274-311 -> 284-365.
- type_aliases.md: 40-81 -> 13-87 + 89-160 + 284-365 (the alias
  table + decision pattern 2.5 + boundary/anti-pattern sections).
