DrSmoothl 455763f109 test(onebot): stop leaking runtime state into the package root
Running the suite left an untracked `packages/onebot/config/onebot_<uin>.json`
in the worktree. The manager's real session-start path materializes a default
per-UIN config, and that path is resolved against cwd — which vitest sets to the
package root. Tests that inject a fake instance still went through it, so the
file (holding a generated access token) reappeared on every run and a
`git add -A` would have committed it.

Run each forked test process from its own temp dir, and fail the file if the
package root gains an entry anyway.
