docs: add AI Coding Assistants documentation

Add guidance for AI assistants and developers using AI tools for kernel
contributions, per the consensus reached at the 2025 Maintainers Summit.

Create Documentation/process/coding-assistants.rst with detailed guidance
on licensing, Signed-off-by requirements, and attribution format. The
README points AI tools to this documentation.

This will allow coding assistants to easily parse these instructions and
comply with guidelines set by the community.

+AI Coding Assistants
+++++++++++++++++++++
+
+This document provides guidance for AI tools and developers using AI
+assistance when contributing to the Linux kernel.
+
+AI tools helping with Linux kernel development should follow the standard
+kernel development process:
+
+* Documentation/process/development-process.rst
+* Documentation/process/coding-style.rst
+* Documentation/process/submitting-patches.rst
+
+Licensing and Legal Requirements
+================================
+
+All contributions must comply with the kernel's licensing requirements:
+
+* All code must be compatible with GPL-2.0-only
+* Use appropriate SPDX license identifiers
+* See Documentation/process/license-rules.rst for details
+
+Signed-off-by and Developer Certificate of Origin
+=================================================
+
+AI agents MUST NOT add Signed-off-by tags. Only humans can legally
+certify the Developer Certificate of Origin (DCO). The human submitter
+is responsible for:
+
+* Reviewing all AI-generated code
+* Ensuring compliance with licensing requirements
+* Adding their own Signed-off-by tag to certify the DCO
+* Taking full responsibility for the contribution
+
+Attribution
+===========
+
+When AI tools contribute to kernel development, proper attribution
+helps track the evolving role of AI in the development process.
+Contributions should include an Assisted-by tag in the following format::
+
+  Assisted-by: AGENT_NAME:MODEL_VERSION [TOOL1] [TOOL2]
+
+Where:
+
+* ``AGENT_NAME`` is the name of the AI tool or framework
+* ``MODEL_VERSION`` is the specific model version used
+* ``[TOOL1] [TOOL2]`` are optional specialized analysis tools used
+  (e.g., coccinelle, sparse, smatch, clang-tidy)
+
+Basic development tools (git, gcc, make, editors) should not be listed.
+
+Example::
+
+  Assisted-by: Claude:claude-3-opus coccinelle sparse
