simplify: drop _should_route_to_error_handler, remove functional API error handler, clean up prepare_node_error_handler_task signature

Replace the hidden __error_handler__<name> node approach with a
callable field on PregelNode/PregelExecutableTask, matching how
retry_policy and cache_policy work:

- error_handler: Runnable | None lives on StateNodeSpec, PregelNode,
  and PregelExecutableTask — no separate node registration at compile time
- ErrorHandlerNode type alias added to _node.py covering the common
  handler signatures (state + NodeError, runtime + NodeError, etc.)
- Handler task is synthesized at runtime in schedule_error_handler using
  the failed task's write pipeline (failed_task.writers), so no separate
  PregelNode is needed
- compile(error_handler=...) adds a graph-level fallback handler;
  per-node handlers take precedence
- @task(error_handler=...) in the functional API uses inline try/except
  wrapping so the caller's future always resolves to a value
- interrupt_before/after ["__error_handler__<node>"] still works via
  updated validate() and _validate.py checks
- RunnableCallable gains takes_input flag so handlers whose only
  parameters are injected kwargs (e.g. def h(error: NodeError) -> T)
  are called without a spurious positional input arg

 By default `langgraph-checkpoint-postgres` installs `psycopg` (Psycopg 3) without any extras. However, you can choose a specific installation that best suits your needs [here](https://www.psycopg.org/psycopg3/docs/basic/install.html) (for example, `psycopg[binary]`).
 
+## Security
+
+> [!IMPORTANT]
+> Set `LANGGRAPH_STRICT_MSGPACK=true` or pass an explicit `allowed_msgpack_modules` list when creating your checkpointer. This restricts checkpoint deserialization to known-safe types, preventing code execution if the database is compromised. See the [langgraph-checkpoint README](https://github.com/langchain-ai/langgraph/tree/main/libs/checkpoint#serde) for details.

+> [!IMPORTANT]
+> Set `LANGGRAPH_STRICT_MSGPACK=true` or pass an explicit `allowed_msgpack_modules` list when creating your checkpointer. This restricts checkpoint deserialization to known-safe types, preventing code execution if the database is compromised.

+

+  deserializes only the rows the merged walk visits, freeing each blob
+  before advancing.
+* No separate blob table — `channel_values` lives inline in the

+* Single merged walk (not K independent walks): each visited cid is
+  deserialized exactly once, regardless of how many channels are still
+  seeking their seed.
+
+The streaming design keeps peak in-flight memory at roughly one
+deserialized checkpoint at a time, instead of holding the entire
+ancestor chain's worth of raw blobs as a `fetchall()`-materialized list.

+Mirrors `libs/langgraph/tests/test_delta_channel_migration.py` (which
+covers `InMemorySaver` + a third-party fallback to the base default
+impl). This file exercises the same migration scenario through the
+sqlite-specific `SqliteSaver.get_delta_channel_history` override —
+specifically that the streaming ancestor walk finds a pre-migration
+plain `channel_values[ch]` entry and surfaces it as the `seed`, with
+post-migration writes folding on top through the reducer.
+
+Pre-migration checkpoints under `BinaryOperatorAggregate` carry the
+full accumulated value at every settled super-step boundary. The
+override has to identify those as "real" seeds (not `_DeltaSnapshot`
+sentinels) — the saver layer is intentionally delta-agnostic and just
+returns whatever is stored in `channel_values[ch]`.

 `langgraph_checkpoint` also defines protocol for serialization/deserialization (serde) and provides an default implementation (`langgraph.checkpoint.serde.jsonplus.JsonPlusSerializer`) that handles a wide variety of types, including LangChain and LangGraph primitives, datetimes, enums and more.

New applications should set the environment variable `LANGGRAPH_STRICT_MSGPACK=true` or pass an explicit `allowed_msgpack_modules` list to `JsonPlusSerializer` to restrict deserialization to known-safe types.

 ### Pending writes
 
 When a graph node fails mid-execution at a given superstep, LangGraph stores pending checkpoint writes from any other nodes that completed successfully at that superstep, so that whenever we resume graph execution from that superstep we don't re-run the successful nodes.

+
+    !!! warning "Beta"
+
+        `DeltaChannel` is in beta. The API and on-disk representation may
+        change in future releases. Threads written with `DeltaChannel` today
+        are expected to remain readable, but the surrounding contract
+        (`BaseCheckpointSaver.get_delta_channel_history`, the
+        `_DeltaSnapshot` blob shape, the `counters_since_delta_snapshot`
+        metadata field) is not yet stable.
+
+    The reducer receives the current accumulated value and a batch of writes
+    in one call: `reducer(state, [write1, write2, ...]) -> new_state`.
+
+    Reducers must be deterministic and batching-invariant (associative across
+    folds): applying two consecutive write batches separately must produce the
+    same state as applying their concatenation once:
+
+        reducer(reducer(state, xs), ys) == reducer(state, xs + ys)
+
+    This lets LangGraph replay checkpointed writes in larger batches than they
+    were originally produced without changing reconstructed state.
+
+    Snapshot cadence is driven by two counters: per-channel update count and
+    total supersteps since last snapshot. `create_checkpoint` writes a full
+    `_DeltaSnapshot` blob when EITHER the update count reaches
+    `snapshot_frequency` OR the supersteps count reaches the system-wide
+    `DELTA_MAX_SUPERSTEPS_SINCE_SNAPSHOT` bound (default 5000), bounding
+    replay depth even for channels that stop receiving writes.
+
+    Parameters:
+        reducer: `(state, list[writes]) -> new_state`. Must be deterministic
+            and batching-invariant as described above.
+        typ: The value type (e.g. `list`, `dict`). Inferred automatically
+            from the outer type when used inside `Annotated[T, DeltaChannel(...)]`.
