## Description
Mirrors a server-side change by accepting an optional \`metadata\`
filter on \`crons.search\` and \`crons.count\` in both the async and
sync Python SDK clients. Matches the existing pattern used for
assistants/threads search.
## Release Note
Python SDK: \`crons.search\` and \`crons.count\` now accept an optional
\`metadata\` filter that is forwarded to the server.
## Test Plan
- [ ] New unit tests in \`tests/test_crons_client.py\` verify metadata
is forwarded for both async and sync clients and omitted when not
provided.

Adds a first-class `return_minimal` option to the Python
`threads.update` clients. When enabled, the SDK sends `Prefer:
return=minimal` and returns `None` for the 204 response. Covers both
async and sync clients with focused tests.
## Summary
- Adds a `langsmith_tracing` parameter to `runs.create()`,
`runs.stream()`, and `runs.wait()` on both async and sync SDK clients
- Accepts a `LangSmithTracing` TypedDict with optional `project_name`
and `example_id` fields
- Maps to the server's existing `langsmith_tracer` payload key, enabling
users to route traces to specific LangSmith projects or associate with
dataset examples from the SDK
## Test plan
- [x] Unit tests verify payload serialization (langsmith_tracing →
langsmith_tracer mapping)
- [x] Unit tests verify key is excluded when param not provided
- [x] Unit tests verify partial configs (project_name only) work
- [x] API parity tests pass (async/sync client signatures match)
- [x] Full test suite passes (86 tests)
- [x] Lint + type check pass
Release Notes: Added `langsmith_tracing` parameter to `runs.create()`,
`runs.stream()`, and `runs.wait()` in the Python SDK, allowing users to
route traces to a specific LangSmith project or associate with a dataset
example.

Additional guidelines:
- Make sure optional dependencies are imported within a function.
- Please do not add dependencies to `pyproject.toml` files (even
optional ones) unless they are **required** for unit tests.
- Most PRs should not touch more than one package.
- Changes should be backwards compatible.

**Description:** The crons create endpoint supports an end-time field
that is not currently supported in the client. Adding that parameter
here.

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:** Provide the id of the event for routes that use SSE
streams. This will allow for more custom retry logic when streams
disconnect if needed.

**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

**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.
**Issue:** N/A
**Dependencies:** None

## Summary
- add a public accessor for the last received SSE event id
- retry async and sync SSE streams using the Location reconnect path and
Last-Event-ID while skipping empty events
- add regression tests that simulate interrupted SSE streams for both
async and sync clients
## Testing
- make format
- make lint
- make test
