ToolCallLocation.path and Diff.path emitted over ACP must be absolute and POSIX-style per the v1 spec (tool-calls.mdx:304-306). The previous code used platform-specific `node:path` which on Windows prepends the drive letter (e.g. "D:\...") to POSIX-style inputs like "/Users/test/project" — silently corrupting paths emitted to ACP clients on Windows hosts. CI runs on Linux so the latent issue went undetected. Switch to `node:path/posix` so the path normalisation is host-OS independent. Co-Authored-By: Claude <noreply@anthropic.com>

// Diff.path to be absolute, and the wire format is POSIX-style regardless of

// the host OS. Using the platform-specific `node:path` here would prepend the

// "/Users/test/project" — silently corrupting paths emitted to ACP clients.
