* feat(schema): accept reasoning_content as inbound alias for reasoning
Interleaved-thinking clients (cogito, vLLM/DeepSeek-style) emit reasoning_content
on assistant turns. Accept it as an inbound alias so reasoning survives the
tool-result loop; canonical reasoning wins when both are present. Emission is
unchanged (still reasoning).

* feat(anthropic): emit thinking blocks with synthetic signature on tool turns
Extract buildAnthropicContentBlocks so non-streaming content assembly is
unit-testable, and prepend a thinking block (with an opaque synthetic
signature) before text/tool_use blocks when the request opts into thinking.

* feat(anthropic): stream thinking_delta and signature_delta before tool_use
Extract anthropicStreamSequence so the streaming block order is unit-testable,
and emit content_block_start(thinking) -> thinking_delta -> signature_delta ->
content_block_stop before the tool_use block sequence when thinking is enabled.

* docs: add interleaved thinking with tool calls guide
Add a features guide describing interleaved thinking: an assistant turn
carrying reasoning and tool_calls together, the reasoning-round-trip
contract (including the reasoning_content inbound alias and Anthropic
thinking blocks with a synthetic signature), per-backend enablement
(reasoning_format for llama.cpp, reasoning_parser/tool_call_parser for
vLLM/SGLang plus the vLLM auto-config hook), a worked request/response
example, and known limitations. Cross-link from model-configuration,
text-generation, and openai-functions.
