release(core): 1.7.0 (#41418) Releases #41257: tool-call args now stream as `tool-call-delta` slices instead of `block-delta` snapshots of the args so far. Stream consumers have read `tool-call-delta` since 1.6.13 (#41246). Minor, not patch, because the stream's output changes. Code that reads raw `block-delta` args mid-stream should read `tool-call-delta` instead; pin `langchain-core<1.7` to keep snapshots. `.tool_calls.get()` and `.output` are unchanged. Opened with Claude Code.

feat(core): emit `tool-call-delta` for streamed tool-call args (#41257) Depends on #41246 (this PR is stacked on it) and langchain-ai/agent-protocol#102 Related: #40998 --- The chat-model event bridge now streams tool-call args as `tool-call-delta` slices instead of `block-delta` snapshots of the args so far. A 64k-char `write_file` call streamed in 16-char chunks drops from about 129 MB of events to 0.5 MB. - A call's `id`, `name` and provider `index` go on `content-block-start`. `extras`, and an `id` or `name` that arrives later, go on `content-block-finish`. - Each delta is a new object. Before, `PIIMiddleware` redacted the bridge's own copy of the args in place, and under async streaming the tool ran with `{}`. This stays a draft until `langchain-protocol` 0.0.20 is on PyPI and `uv.lock` is refreshed. ## Release note Tool-call args now stream as `tool-call-delta` slices. Upgrade clients first: the JS SDK and its bindings, and `langchain-core` in any Python client. Then upgrade `langchain` and `langchain-core` together on the server. Implemented with Claude Code.
