ci: support native Windows Crabbox daemon hydration

[steipete]

Summary

• Keep the default Crabbox hydrate job compatible with local Actions replay and custom marker jobs.
• Add a separate hydrate-windows-daemon GitHub-runner job for native Windows daemon proof.
• Persist Node/pnpm/PATH handoff files for native Windows and write GitHub command files as UTF-8.
• Avoid forcing pnpm copy imports during Windows hydrate so the final native Windows hydrate completes in 8m instead of the prior 17m run.

Verification

• pnpm test test/scripts/package-acceptance-workflow.test.ts
• node -e "const fs=require('fs'); const yaml=require('yaml'); for (const file of ['.github/workflows/crabbox-hydrate.yml','.crabbox.yaml']) yaml.parse(fs.readFileSync(file,'utf8'));"
• git diff --check
• /Users/steipete/Projects/agent-scripts/skills/autoreview/scripts/autoreview --mode branch --base origin/main --prompt-file /tmp/openclaw-autoreview-context.md
• Crabbox producer fix landed first: fix: stop native Windows hydrate runners crabbox#172, commit 68c60db, so native Windows crabbox stop writes the hydrate .stop marker.

Real behavior proof
Behavior addressed: native Windows Crabbox GitHub-runner hydration for focused OpenClaw daemon E2E proof.
Real environment tested: AWS Crabbox native Windows lease cbx_d5ac8185713b (windows-hydrate-tip), instance m7i.4xlarge, OpenClaw branch fix/windows-crabbox-hydrate at 7bfe3d4b.
Exact steps or command run after this patch: go run ./cmd/crabbox actions hydrate --provider aws --target windows --windows-mode normal --id windows-hydrate-tip --repo openclaw/openclaw --workflow .github/workflows/crabbox-hydrate.yml --ref fix/windows-crabbox-hydrate --job hydrate-windows-daemon --github-runner --keep-alive-minutes 30 --wait-timeout 60m -f ref=refs/heads/fix/windows-crabbox-hydrate --timing-json.
Evidence after fix: Actions run https://github.com/openclaw/openclaw/actions/runs/26492495359 completed hydration; Crabbox reported actions hydrate complete total=8m0.804s with actionsRunUrl set to that run.
Observed result after fix: follow-up crabbox run --no-sync reused workspace=actions-hydrated and printed pnpm 11.2.2, node v24.16.0, 7bfe3d4b, fix/windows-crabbox-hydrate; run id run_71f59c1fcbee.
What was not tested: broad OpenClaw CI on this branch; this PR only changes the hydrate workflow/test surface.
