style(retain): format long function call arguments one-per-line

- Class docstring now clearly documents async-first pattern: a* methods
  preferred, sync wrappers for scripts/REPLs only
- Every sync method docstring points to its async counterpart
- Every async method docstring says "preferred"
- Expose 10 low-level API properties (documents, entities, operations,
  webhooks, monitoring, etc.) so agents/users can discover the full API
  surface without guessing at _-prefixed internals
- Add missing API parameters: tag_groups (recall/reflect), fact_types,
  exclude_mental_models, exclude_mental_model_ids (reflect),
  observation_scopes/strategy (retain items), background (create_bank)
- Fix areflect missing include_facts param that sync reflect already had
- Sync recall/reflect now delegate to async counterparts (no logic duplication)

     High-level, easy-to-use Hindsight API client.
 
-    Example:
-        ```python
+    This class provides simplified methods for the most common operations:
+    retain, recall, reflect, bank management, mental models, and directives.
+
+    **Async vs sync:** Every convenience method has an async counterpart
+    prefixed with ``a`` (e.g. ``aretain``, ``arecall``, ``areflect``).
+    **Prefer the async variants** (``aretain``, ``arecall``, ``areflect``, etc.)
+    whenever you are inside an async context (``async def``, event loops,
+    frameworks like FastAPI/LangGraph/CrewAI). The sync versions (``retain``,
+    ``recall``, ``reflect``) are convenience wrappers that call
+    ``asyncio.run_until_complete`` under the hood — they exist for scripts and
+    REPLs but will raise errors if an event loop is already running.
+
+    For operations not covered here (documents, entities, operations/async jobs,
+    webhooks, file uploads, monitoring), use the low-level API clients exposed
+    as properties on this class. These are auto-generated from the OpenAPI spec
+    and cover the full API surface. **All low-level methods are async-only.**
+
+    Example — async (preferred)::
+
         from hindsight_client import Hindsight
 
-        # Without authentication
-        client = Hindsight(base_url="http://localhost:8888")
-
-        # With API key authentication
         client = Hindsight(base_url="http://localhost:8888", api_key="your-api-key")
 
-        # Store a memory
+        # Inside an async function — use the a* methods
+        await client.aretain(bank_id="alice", content="Alice loves AI")
+        response = await client.arecall(bank_id="alice", query="What does Alice like?")
+        answer = await client.areflect(bank_id="alice", query="What are my interests?")
+
+    Example — sync (scripts / REPLs only)::
+
+        # Outside an async context — sync wrappers are available
         client.retain(bank_id="alice", content="Alice loves AI")
-
-        # Recall memories
         response = client.recall(bank_id="alice", query="What does Alice like?")
-        for r in response.results:
-            print(r.text)
 
-        # Generate contextual answer
-        answer = client.reflect(bank_id="alice", query="What are my interests?")
-        ```
+    Example — low-level API for advanced operations::
+
+        # Access documents, entities, operations, webhooks, etc.
+        # All low-level methods are async-only — use 'await' or asyncio.run().
