## Summary
Wraps every caller-supplied identifier (thread_id, assistant_id, run_id,
cron_id, checkpoint_id, namespace) interpolated into request URL paths
with `urllib.parse.quote(safe="")` via a new `_quote_path_param` helper.
All-dot strings are encoded as `%2E` triplets so they aren't collapsed
by httpx's client-side path normalization. Helper raises `TypeError` for
None/bytes inputs.
## Test plan
- [x] `make format` / `make lint` / `make test` from `libs/sdk-py`
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 `extract` parameter to `threads.search()` in both async and sync
clients
- Adds `extracted` field to the `Thread` TypedDict response type
- The `extract` parameter accepts a `dict[str, str]` mapping aliases to
JSONB paths (e.g., `{"last_msg": "values.messages[-1]"}`)
- Depends on server-side support in
https://github.com/langchain-ai/langgraph-api/pull/2609
## Test plan
- [ ] Verify types are correct via lint/format (already passing)
- [ ] Integration test against server with extract feature enabled
Release Notes: Add `extract` parameter to `threads.search()` for
extracting nested values from thread data during search.

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.
