Title: `get_job` and `job_logs` return "not found" for jobs visible via `list_jobs --allScopes`

[caleb-reyes-op]

Summary

When a job is created with a workdir in another scope, list_jobs --allScopes correctly shows the job, but get_job and job_logs fail with not found in the current session scope.
This makes it hard to inspect or run jobs from a control-plane repo that intentionally schedules jobs for a different runtime repo.

Environment

• Scheduler plugin: opencode-scheduler@1.3.0
• Opencode binary: /Users/caleb/.nix-profile/bin/opencode
• Opencode version: 1.2.27
• OS: macOS (darwin)

Reproduction

1. From a control-plane directory/session, create a job with a different runtime workdir:
   • name: weekday-standup-10am
   • command: /Users/caleb/Coding/opencode-scheduler/jobs/weekday-standup-10am/run.sh
   • workdir: /Users/caleb/Coding/web
2. Run list_jobs with allScopes=true and includeLegacy=true.
3. Confirm the job appears in the output.
4. Run:
   • get_job name=weekday-standup-10am
   • job_logs name=weekday-standup-10am

Actual Behavior

Both commands return:

• Job "weekday-standup-10am" not found.
  Even though list_jobs --allScopes shows the job.

Expected Behavior

One of the following:

1. get_job/job_logs should resolve uniquely across scopes (when name is unique), or
2. get_job/job_logs should accept scopeRoot / scopeId / allScopes parameters similar to list_jobs, or
3. Error should indicate the job exists in a different scope and show that scope explicitly.

Additional Context

• list_jobs with scopeRoot=/Users/caleb/Coding/web shows the job.
• Job definition exists on disk under scheduler scope storage (e.g. ~/.config/opencode/scheduler/scopes/<scope-id>/jobs/weekday-standup-10am.json).
• This currently blocks lifecycle checks like "get details", "run immediately", and "view logs" from a central scheduler repo.
