Adding support for the `context` arg to `invoke/stream` to the sdk. This
is paired with an update to the API as well that adds `context` support
to the `assistants` and `runs` endpoints.
Bumping version to v0.2.0 on the `v1` branch given this and the
interrupt schema changes.
- Replaces checkpoint_during: bool
- checkpoint_during is deprecated but still respected
- We implement three durability modes (from least to most durable):
- "exit" - save checkpoint only when the graph exits (equivalent to
checkpoint_during=False)
- "async" - save checkpoint asynchronously while the next step executes
(the default, equivalent to old checkpoint_during=True)
- "sync" - save checkpoint synchronously before the next step starts
(new mode, slower but most durable)

* Cleaning up the underlying tool injection logic which is happening in
multiple locations.
* State was being injected into the ToolCall via Send in two places in
create react agent and the logic doesn't belong there, the actual
injection should be happening inside the ToolNode where there's
awareness of what run time parameters the tool accepts.
Change is required to unblock:
https://github.com/langchain-ai/langgraph/pull/5537
Fixes#5554
This PR removes unused utility classes and functions from the prebuilt
tests directory to clean up dead code.
Changes include:
- Removed unused classes from `libs/prebuilt/tests/any_str.py`:
- Deleted FloatBetween, AnyDict, AnyVersion, and UnsortedSequence
- Kept only AnyStr class
- Removed unused functions from `libs/prebuilt/tests/messages.py`:
- Deleted _AnyIdDocument and _AnyIdAIMessageChunk
- Kept _AnyIdHumanMessage and _AnyIdToolMessage
- Removed unused classes from `libs/prebuilt/tests/memory_assert.py`:
- Deleted NoopSerializer, MemorySaverAssertCheckpointMetadata, and
MemorySaverNoPending
- Kept MemorySaverAssertImmutable
Verification:
- Manually checked for no remaining references to removed code
- Maintained existing import structures
- Preserved functionality of the prebuilt test suite
The changes reduce code complexity and remove unnecessary utility
classes that were not being used in the test suite.

- Channels containing primitive values don't need to be stored in separate rows in blobs table, as the overhead of a separate row will usually be higher than the size of the value
- This applies for instance to all internal channels used to manage edges, so it has a big impact just from that. It can also apply to user-managed channels depending on their values
- The same channel may switch storage between versions without any issue

This commit fixes#5503
Gist of it is:
- `asyncio.exception.InvalidStateError` were being raised when the
future was cancelled
- this exception bubbled up and killed the background task
- `AsyncBatchedBaseStore` stopped doing queries because the background
task wasn't running anymore
This commit adds some "if future is not done" checks to guard against
this.
