fix(core): strip null id/name from tool-call-chunk deltas in compat bridge Many provider integrations (notably Anthropic's `input_json_delta` path) attach the tool-call `id` and `name` only to the first `tool_use` chunk; subsequent per-chunk slices carry `id=None, name=None` and just the fresh `args` segment. The compat bridge forwarded those `None` values verbatim, producing wire payloads like `{"type": "tool_call_chunk", "id": null, "name": null, "args": "..."}`. Consumers that fold deltas via a naive `{...target, ...delta}` spread (e.g. the langgraph-js SDK's `MessageAssembler.applyContentDelta`) interpret those as "identifier reset to null" and lose the id/name captured from `content-block-start`. Downstream extractors then drop the chunk until the final `content-block-finish` arrives — visible to end users as tool-call cards appearing all-at-once at the end of a turn instead of streaming in incrementally (the Deep Agent example rendering four subagents in a single flicker rather than one after another). Introduce `_to_protocol_delta_block` and route every `content-block-delta` emission (sync / async chunk streams and the `message_to_events` replay path) through it. For `tool_call_chunk` and `server_tool_call_chunk` shapes, drop `id` / `name` keys when they would serialize to `null`. This matches the wire shape produced by langgraph-js's `toProtocolDeltaBlock`, where identifiers are only surfaced when they carry a real value.
