Add support for the http.apps config field in langgraph.json that lets
users mount multiple HTTP apps at different path prefixes alongside the
built-in LangGraph API.
Config format:
{
"http": {
"app": "./custom_routes.py:app",
"apps": {
"/dashboard": "./dashboard.py:app",
"/ext": "./extension.js:app",
"/conduit": "some-npm-package:app"
}
}
}
Changes:
- Add apps: dict[str, str] | None to HttpConfig TypedDict in schemas.py
- Add validation for http.apps entries (prefix must start with /, values
must be module:attribute format)
- Add _update_http_apps_paths() for Docker container path rewriting
- Add _is_js_http_app() and _has_js_http_apps() helpers for JS detection
- Ensure Node.js is installed in Docker images when JS HTTP apps present
- Regenerate JSON schema files

## Summary
- The config processing code in `config.py` already handles graphs
defined as `{"path": "...", "description": "..."}` dicts, but the
`Config` TypedDict and JSON schema only declared `dict[str, str]`
- Added a `GraphDef` TypedDict with `path` and optional `description`
fields
- Updated `Config.graphs` to `dict[str, str | GraphDef]` and regenerated
the JSON schemas
- This makes the schema match the actual runtime behavior and fixes
IDE/schema validation for users who use the dict format
## Test plan
- [x] `make format` passes
- [x] `make lint` passes
- [x] `make test` passes (all 85 tests)
- [x] Schema regeneration produces consistent output
Release Notes: Update `langgraph.json` schema to support `{"path":
"...", "description": "..."}` format for graph definitions.

## Summary
- Add `"keep_latest"` to `ThreadTTLConfig.strategy` to match
langgraph-api support for pruning old checkpoints while retaining the
thread and its latest state
- Add `sweep_limit` to `ThreadTTLConfig` where the API actually reads it
(was previously a no-op on `CheckpointerConfig`)
- Regenerate `schema.json` / `schema.v0.json`
## Test plan
- [x] `make format && make lint` passes
- [x] `make test` passes (85/85)

**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
