fix(gateway): sync plugin override protocol artifacts

Regeneration-Prompt: |
  Rebase PR #48277 onto current origin/main without changing its intent: gateway-owned plugin subagent runs should be able to forward per-run provider and model overrides through the internal agent RPC, while admin-only gating stays in the gateway agent handler.

  After rebasing, keep the PR scoped to prep fallout instead of broad unrelated cleanup. Commit the generated Swift protocol models required by adding provider/model to AgentParams, add the required Unreleased changelog entry, and update the new commands/agent test fixture so the explicit openai/gpt-4.1-mini override is allowed under the current model allowlist rules. Do not fold in unrelated existing main-branch test failures.

@@ -112,6 +112,7 @@ Docs: https://docs.openclaw.ai
 - Control UI/storage: scope persisted settings keys by gateway base path, with migration from the legacy shared key, so multiple gateways under one domain stop overwriting each other's dashboard preferences. (#47932) Thanks @bobBot-claw.
 - Agents/usage tracking: stop forcing `supportsUsageInStreaming: false` on non-native OpenAI-completions providers so compatible backends report token usage and cost again instead of showing all zeros. (#46500) Fixes #46142. Thanks @ademczuk.
 - Plugins/subagents: preserve gateway-owned plugin subagent access across runtime, tool, and embedded-runner load paths so gateway plugin tools and context engines can still spawn and manage subagents after the loader cache split. (#46648) Thanks @jalehman.
+- Plugins/subagents: forward per-run provider and model overrides through gateway plugin subagent dispatch so plugin-launched agent delegations honor explicit model selection again. (#48277) Thanks @jalehman.
 - Control UI/overview: keep the language dropdown aligned with the persisted locale during dashboard startup so refreshing the page does not fall back to English before locale hydration completes. (#48019) Thanks @git-jxj.
 - Agents/compaction: rerun transcript repair after `session.compact()` so orphaned `tool_result` blocks cannot survive compaction and break later Anthropic requests. (#16095) thanks @claw-sylphx.
 - Agents/compaction: trigger overflow recovery from the tool-result guard once post-compaction context still exceeds the safe threshold, so long tool loops compact before the next model call hard-fails. (#29371) thanks @keshav55.
