feat(agent-loop): open every prompt with the harness identity section

A static harness:identity section at order -100 — the first occupant of
the documented negative band — states that the agent is powered by the
DeepSeek Harness SDK before the deployment's persona renders. Harness
attribution is a harness fact: it lives on the loop plugin, not in each
deployment's persona, so every agent (subagents included) carries it and
no YAML can forget it. A deployment that must drop it can remove the
section in the system-prompt/assemble waterfall.

Order-band docs updated in all five homes (PromptSection JSDoc, the
system-prompt and agent-loop READMEs, architecture.md, the RFC).

## Prompt assembly (dsh-system-prompt)
Plugins contribute `PromptSection`s (named, ordered, static or computed from the per-call `AssembleContext`), tool-schema providers, and named **prompt variables** interpolated as `{{name}}` at render (strict: an unknown or valueless reference throws). `renderPrompt(assemble({ agent }))` IS the full prompt: the loop's `agent:persona` section (order 0) and its `model`/`cwd` variables carry the per-agent facts — no second composition path. Tool schemas are deliberately part of the assembly ([RFC](rfc/implemented/architecture/2026-06-11-tool-schemas-in-prompt-assembly.md)); prompt-fact ownership (persona vs description vs section vs variable) is pinned by [the prompt-variables RFC](rfc/implemented/architecture/2026-07-05-prompt-variables-and-tool-guidance-ownership.md).
