Add automated workflow update action (#1)

* Initial plan

* Add update-workflows GitHub Action

- Installs gh-aw extension using official installation script
- Runs gh aw update to update workflow definitions
- Runs gh aw compile to compile workflows
- Automatically commits and pushes any changes
- Scheduled to run weekly on Sundays
- Can be manually triggered via workflow_dispatch

* Address review feedback

- Remove gh CLI installation step (always installed on runners)
- Replace 'gh aw update' with 'gh aw init'
- Update commit message to reflect gh aw init

* Randomize cron schedule minute

- Changed from "0 0 * * 0" to "23 0 * * 0"
- Runs at 00:23 UTC instead of 00:00 UTC to avoid load spikes
