fix: typo: saved the world "BaseMessge" to "BaseMessage" ( #6639 )
...
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.

fix(sdk-py): remove model-type specific custom json encryption annotations & document key preservation limitations ( #6595 )
...
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.

Includes shared validation logic and a regression test so we don’t see

**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:**
- [depended upon by associated langgraph-api
changes](https://github.com/langchain-ai/langgraph-api/pull/1773 )(this
PR must merge before that one)
- [docs PR](https://github.com/langchain-ai/docs/pull/1715 )
**TODO:**
- [x] move docs to docs repo
- [x] bump package versions before merge

feat(sdk-py): add sentinel to skip auto loading api key on sdk client create ( #6500 )

**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.

fix: interrupt stream mode values ( #6475 )
...
This PR improves the consistency of interrupt streaming.
- when streaming with stream_mode values, the stream chunk now contains
the entire state alongside the interrupt:
```python
class State(TypedDict):
robot_input: str
# at this point in time robot_input is already set to "beep boop i am a robot"
app.stream(..., stream_mode="values")
# before
{"__interrupt__": (Interrupt(value="interrupt",))}}
# after
{"robot_input": "beep boop i am a robot", "__interrupt__": (Interrupt(value="interrupt"))}
```
- when streaming with stream_mode=["values", "updates"], interrupts are
surfaced in both an update stream chunk and the value stream chunk, when
previously we keep interrupt in values only if we request values mode
only
```python
class State(TypedDict):
robot_input: str
# at this point in time robot_input is already set to "beep boop i am a robot"
app.stream(..., stream_mode=["values", "updates"])
# before (interrupt would only emit on update chunk, there would be no values chunk)
("updates", {"__interrupt__": (Interrupt(value="interrupt",))}})
# after
("updates", {"__interrupt__": (Interrupt(value="interrupt",))}})
("values", {"robot_input": "beep boop i am a robot", "__interrupt__": (Interrupt(value="interrupt"))})
```

fix: refactor injection logic to respect function signatures ( #6468 )
...
## overview
The main purpose of this is to respect tool signatures that request
injected args (like `ToolRuntime`) even when the explicitly specified
`args_schema` does not.
Ex in the following example, we should still inject `runtime` despite
its absence in `ArgsSchema`
```py
class ArgsSchema(BaseModel):
some_arg: int = Field(...)
@tool(args_schema=ArgsSchema)
def my_tool(some_arg: int, runtime: ToolRuntime): ...
```
This is accompanied by
https://github.com/langchain-ai/langchain/pull/34051 which has tests
that pass w/ this change. This tests injection w/ `create_agent` (more
end to end than tests added in
https://github.com/langchain-ai/langchain/pull/33999 .
This unblocks the injection of `ToolRuntime` into MCP tools which is
exciting bc that exposes tool call id and state, which we previously
were unable to do.
## other benefits
* Cleaner code structure w/ more helpful docs about injected args.
* Nice perf boost, we're no longer inspecting the annotations of a
tool's schema 3 different times to detect store, state, and runtime
injections.
## additional notes
1. I could see a world where we want more of this logic to reside on the
tools themselves, but tools don't now about LG specific injection types
(like `ToolRuntime`, hence having this logic here for now).
2. We could separately add validation for the case where something is
specified in `args_schema` and not in the function signature (probably
at the tool level though).

fix: deprecate setattr on ToolCallRequest ( #6462 )

* one alternative considered was setting `frozen=True` on the dataclass,
but this is breaking, so a deprecation is a nicer approach

refactor: separate prepare_push_* functions ( #6450 )
...
Extract two common cases from the big switch statement of
`prepare_single_task` since it's a tad more composable.
All this does is shift/extract code to separate functions
