fix: use npm for bundled runtime dep repair

CHANGELOG.md

@@ -30,6 +30,7 @@ Docs: https://docs.openclaw.ai
 - OpenAI/Responses: resolve `/think` levels against each GPT model's supported reasoning efforts so `/think off` no longer becomes high reasoning or sends unsupported `reasoning.effort: "none"` payloads.
 - Lobster/TaskFlow: allow managed approval resumes to use `approvalId` without a resume token, and persist that id in approval wait state. (#69559) Thanks @kirkluokun.
 - Plugins/startup: install bundled runtime dependencies into each plugin's own runtime directory, reuse source-checkout repair caches after rebuilds, and log only packages that were actually installed so repeated Gateway starts stay quiet once deps are present.
+- Plugins/startup: ignore pnpm's `npm_execpath` when repairing bundled plugin runtime dependencies so npm-only install flags are not passed to pnpm-launched gateways.
 - Setup/TUI: relaunch the setup hatch TUI in a fresh process while preserving the configured gateway target and auth source, so onboarding recovers terminal state cleanly without exposing gateway secrets on command-line args. (#69524) Thanks @shakkernerd.
 - Codex: avoid re-exposing the image-generation tool on native vision turns with inbound images, and keep bare image-model overrides on the configured image provider. (#65061) Thanks @zhulijin1991.
 - Sessions/reset: clear auto-sourced model, provider, and auth-profile overrides on `/new` and `/reset` while preserving explicit user selections, so channel sessions stop staying pinned to runtime fallback choices. (#69419) Thanks @sk7n4k3d.
