fix: enable automatic PR creation for agent:codex labels

[stranske]

Root Cause

The workflow was using mode: 'invite' without force_mode, causing the reusable workflow to ignore the mode parameter and prevent automatic bootstrap PR creation when issues are labeled with agent:codex.

From the reusable workflow code (line 257-268), when the event is 'issues', the mode is hardcoded to 'invite' unless force_mode is enabled.

Changes

• Change mode from 'invite' to 'create' in bridge job
• Add force_mode: true to override issue event defaults

This matches the fix from Workflows repo commit bd48949 (PR stranske/Workflows#606) which resolved the same startup_failure issue in other consumer repos.

Testing

After this fix:

1. When an issue is labeled with agent:codex, the workflow will automatically create a bootstrap PR
2. The agent can immediately start working without manual PR creation
3. Workflow will no longer fail with startup_failure
