Add metadata() calls to background_task and call_omo_agent tools so that OpenCode UI displays session navigation hints (ctrl+x + arrow keys) like the original Task tool does. This enhances UX by providing consistent session navigation UI for background and subagent tasks.

Fixes#191
This commit ensures that the user's selected model is preserved when
background tasks complete and notify their parent sessions.
Changes:
- Add parentModel field to BackgroundTask and LaunchInput interfaces
- Capture model context when launching background tasks
- Pass model context when notifying parent sessions after task completion
Impact:
- Users with OAuth providers (Google, Anthropic) will now have their
model selection preserved across background task continuations
- Background agents no longer revert to hardcoded defaults

Previously, background_cancel(all=true) only cancelled direct child tasks, leaving grandchildren and deeper nested tasks uncancelled. This caused background agents to continue running even when their parent session was cancelled.
Changes:
- Added getAllDescendantTasks() method to BackgroundTaskManager for recursive task collection
- Updated background_cancel to use getAllDescendantTasks instead of getTasksByParentSession
- Added comprehensive test coverage for nested task cancellation scenarios

When an invalid or unregistered agent is passed to background_task or
call_omo_agent, OpenCode crashes with "TypeError: undefined is not an
object (evaluating 'agent.name')". This fix:
- Validates agent parameter is not empty before launching
- Catches prompt errors and returns friendly error message
- Notifies parent session when background task fails
- Improves error message to guide user on resolution
