v0.3.1

Bugfix: scope job listings to the current repo.

The job store is global across repos. Previously status, the statusline, and the completion hook showed jobs from every folder — a job running in repo A appeared as running in repo B.

Now each listing filters by the job's recorded cwd:

• /cursor:status lists the current repo's jobs by default; --all shows every folder.
• statusline counts only running jobs in the current repo.
• completion hook announces only jobs under the session cwd.

89 mocked tests, all green.
