docs(openai): document GPT-5.5 defaults

-- `model.primary`: format `provider/model` (e.g. `openai/gpt-5.4`). If you omit the provider, OpenClaw tries an alias first, then a unique configured-provider match for that exact model id, and only then falls back to the configured default provider (deprecated compatibility behavior, so prefer explicit `provider/model`). If that provider no longer exposes the configured default model, OpenClaw falls back to the first configured provider/model instead of surfacing a stale removed-provider default.

 - `models`: the configured model catalog and allowlist for `/model`. Each entry can include `alias` (shortcut) and `params` (provider-specific, for example `temperature`, `maxTokens`, `cacheRetention`, `context1m`).
   - Safe edits: use `openclaw config set agents.defaults.models '<json>' --strict-json --merge` to add entries. `config set` refuses replacements that would remove existing allowlist entries unless you pass `--replace`.
   - Provider-scoped configure/onboarding flows merge selected provider models into this map and preserve unrelated providers already configured.

 - `runtime`: `"auto"`, `"pi"`, or a registered plugin harness id. The bundled Codex plugin registers `codex`.
 - `fallback`: `"pi"` or `"none"`. `"pi"` keeps the built-in PI harness as the compatibility fallback when no plugin harness is selected. `"none"` makes missing or unsupported plugin harness selection fail instead of silently using PI. Selected plugin harness failures always surface directly.
 - Environment overrides: `OPENCLAW_AGENT_RUNTIME=<id|auto|pi>` overrides `runtime`; `OPENCLAW_AGENT_HARNESS_FALLBACK=none` disables PI fallback for that process.
-- For Codex-only deployments, set `model: "codex/gpt-5.4"`, `embeddedHarness.runtime: "codex"`, and `embeddedHarness.fallback: "none"`.

 - Harness choice is pinned per session id after the first embedded run. Config/env changes affect new or reset sessions, not an existing transcript. Legacy sessions with transcript history but no recorded pin are treated as PI-pinned. `/status` shows non-PI harness ids such as `codex` next to `Fast`.
 - This only controls the embedded chat harness. Media generation, vision, PDF, music, video, and TTS still use their provider/model settings.
