feat: insert the daemon context in the poller context

The daemon context is needed when the context of a job or the poller
is done. Otherwise it is no longer possible to send a conclusion
report to Forgejo, short of creating a context.Background() which
poses its own set of problems.

- WithDaemonContext is used to store the daemon context
- The poller uses the daemon context instead of context.Background
