test(workspaces): fix runtime provision metadata assertion (#11707)

## Thinking Path

> - Paperclip manages agent work in isolated execution workspaces.
> - Workspace operations record operation metadata and command-result
metadata separately.
> - Runtime provisioning records its provision kind in the operation
metadata.
> - One merged regression test checked that value in the command-result
metadata.
> - The production behavior was correct, but the test failed.
> - This pull request checks the provision kind in the operation
metadata.
> - The benefit is that the regression test now matches the recorder
contract.

**What happened?**

The runtime provisioning regression test expected `provisionKind` in
`result.metadata`. The recorder stores this value in the operation's
top-level `metadata`. The command-result metadata is `null` for this
case.

**Expected behavior**

The test must check `metadata.provisionKind`. It must continue to check
`result.status`.

**Steps to reproduce**

1. Check out commit `e1df4c6068fea684a1e9714ebd64bce95f3db19a`.
2. Run the focused runtime provisioning test.
3. Observe that the assertion checks the wrong metadata object.

**Deployment mode**

Local development.

## What Changed

- Move the `provisionKind` assertion from `result.metadata` to the
operation's top-level `metadata`.
- Keep the `result.status` assertion unchanged.

## Verification

- `pnpm --filter @paperclipai/server exec vitest run
src/__tests__/workspace-runtime.test.ts -t "keeps an explicit command
matching the built-in seed command as runtime provisioning"`
- Result: 1 test passed and 125 tests skipped.

## Risks

- Low risk. This pull request changes one test assertion and does not
change production code.

> For core feature work, check [`ROADMAP.md`](ROADMAP.md) first and
discuss it in `#dev` before opening the PR. Feature PRs that overlap
with planned core work may need to be redirected — check the roadmap
first. See `CONTRIBUTING.md`.

## Model Used

- OpenAI Codex, GPT-5, high-reasoning mode, with repository, shell, Git,
GitHub, and code execution tools. The runtime does not expose a
context-window value.
