**Description:**
This PR fixes an issue where injection types (like `ToolRuntime`) were
not recognized by `ToolNode` when used with generic type arguments
(e.g., `ToolRuntime[MyContext]`).
Previously, the `_is_injection` check relied solely on `isinstance` and
`issubclass`, which fail for `typing._GenericAlias` objects. This update
adds a check using `typing.get_origin()` to correctly identify the base
class of generic types, ensuring the runtime is injected correctly even
when type hints are present.

25 is pretty unreasonable for most applications, bumping up to 1000 by
default, burden really should be on the user to enforce this based on
their application

Changed "BaseMessge" to "BaseMessage" in test comments.
This critical 2-character fix prevents mass confusion among developers
who might have spent milliseconds wondering what a "Messge" is.
The world is now a safer place.

bumping sdk-py for custom encryption cleanup changes (#6595) - these are
breaking changes on this beta, unreleased and unused feature.
Signed-off-by: Connor Braa <cwlbraa@langchain.dev>
In langgraph-api, custom-encrypted JSONs need to continue to be
SQL-json-mergable after encryption. Previous WIP docs
advocated for custom encryption impls where all encrypted kv pairs were
shoved into a `__encrypted__: $encrypted_kvs` meta-key. Turns out that
pattern causes data loss when running PATCH-style partial updates or in
the many places langgraph-api json-SQL-merges across model types.
This PR contains 2 SDK fixes:
1. remove model-type specific custom json encryption annotations - these
cause surprising behavior as config and context data propagates across
model types, specifically because today we can't guarantee that data
encrypted as one model-type will be decrypted as the same model-type
because kv pairs move across model-types in pure SQL
2. document limitations and validation around "key preservation" in
custom json encryption functions. langgraph-api now validates that
custom JSON encryption fns don't change keys. That validation prevents
customizers from writing custom encryption functions that cause data
loss through patch endpoints and x-model merge propagation.

Description: Catch invalid checkpointer objects early by validating any
checkpointer argument before compilation/execution, raising a clear
TypeError that instructs users to pass a proper BaseCheckpointSaver
(e.g., AsyncPostgresSaver) instead of stores like AsyncPostgresStore.
Includes shared validation logic and a regression test so we don’t see
AttributeError: 'AsyncPostgresStore' object has no attribute
'get_next_version' again.

**Description**: The Agent Server API now supports counting assistants
by name.
This is similar to adding the `name` parameter to the Assistants search
API: https://github.com/langchain-ai/langgraph/pull/6483
**Description:**
This PR adds the Python SDK types necessary for langgraph platform users
to inject their own custom encryption-at-rest functions. See [docs
PR](https://github.com/langchain-ai/docs/pull/1715) for more details.
note: this PR adds a starlette dev dependency so that custom encryption
can access BaseUser information.
**Issue:**
required for LSD-172
**Dependencies:**

changes](https://github.com/langchain-ai/langgraph-api/pull/1773)(this

- [docs PR](https://github.com/langchain-ai/docs/pull/1715)
**TODO:**
- [x] move docs to docs repo
- [x] bump package versions before merge

**Description:** There are times a user might want to create the client,
but conditionally set the API key. For example, consider a complex auth
situation where the system has user callers using jwts and system
callers using API keys. This allows explicitly disabling the
auto-loading behavior of API keys in the client today, so no key is set.

Otherwise, you cannot use `context` with stateful runs, because the
server throws if you provide both configurable and context in a single
call (due to ambiguous parameters)
