## Summary
This updates Pregel callback manager initialization to pass
`tracerInheritableMetadata` defaults derived from `config.configurable`,
and narrows `ensureLangGraphConfig` metadata mirroring to the
allowlisted LangGraph identifiers used in stream/runtime metadata.
## Changes
### `@langchain/langgraph` (`libs/langgraph-core`)
- Updated Pregel callback manager setup to configure core callbacks with
`tracerInheritableMetadata` based on configurable primitive values,
excluding internal and secret-like keys.
- Hoisted tracing default logic into `_getTracingMetadataDefaults` and
`_excludeAsMetadata` for parity with the Python implementation shape.
- Restricted `ensureLangGraphConfig` configurable-to-metadata
propagation to the identifier allowlist:
- `thread_id`
- `checkpoint_id`
- `checkpoint_ns`
- `task_id`
- `run_id`
- `assistant_id`
- `graph_id`
- Updated config tests to assert the narrowed metadata propagation
behavior.

Issue:
In multi-agent sustem with handoffs like this example:
https://docs.langchain.com/oss/python/langchain/multi-agent/handoffs#multiple-agent-subgraphs,
if we trigger an interrupt from an agent within a swarm workflow, the
interrupt is propagated and sent twice, the last interrupt contains
values from the main graphs state, which is always going to be behind
the state of the agent from where interrupt is triggered. So,
temporarily, the message data becomes empty, it gets refilled when
interrupt is resumed
Fixes:
Do not update values when interrupt is recieved, just update the
interrupt in the state with the latest __interrupt data.

## Description
TypeScript 6.0 requires that any type emitted to a declaration file is
reachable via the package's `exports` field. Several types used in
`StateGraph`'s public API (class extends clause, constructor overloads,
method signatures) were not exported from the package entrypoints,
causing TS6 consumers to fail when exporting `StateGraph` instances from
their own packages.
Adds exports for: `ToStateDefinition`, `StateGraphNodeSpec`, `NodeSpec`,
`AddNodeOptions`, `StateGraphAddNodeOptions`,
`StateGraphArgsWithStateSchema`, `StateGraphArgsWithInputOutputSchemas`,
`CachePolicy`, `AnyStateSchema`, `StateSchemaFieldToChannel`,
`StateSchemaFieldsToStateDefinition`.
## Test Plan
- [ ] Verify a TS6 project can export a `StateGraph` instance without
declaration file errors
- [ ] Build passes with `pnpm build`
