Create ROBOT_CODE_DISPATCH_TOKEN for cross-repo CI dispatch

What

Each sibling repo's CI has a repository_dispatch step that notifies robot-code when main advances. This requires a fine-grained PAT stored as an org secret.

Without this token

Cross-repo integration tests only run on:

• PRs to robot-code
• Nightly cron (08:00 UTC)
• Manual workflow_dispatch

Push-to-main on a sibling does NOT trigger integration tests.

Setup steps

1. Create a fine-grained PAT at https://github.com/settings/personal-access-tokens/new

   • Name: ROBOT_CODE_DISPATCH_TOKEN
   • Resource owner: personalrobotics
   • Repository access: personalrobotics/robot-code only
   • Permissions: Contents: Read, Actions: Write
   • Expiration: 90 days (set a calendar reminder to rotate)

2. Add as org secret:

   gh secret set ROBOT_CODE_DISPATCH_TOKEN --org personalrobotics --visibility all
   

3. Test: push a trivial change to any sibling's main and verify robot-code's integration workflow triggers.

Priority

Low — nightly cron catches breakage within 24 hours regardless. This just makes it near-instant.

Follow the PAT and organization-secret setup steps in this issue, using the listed repository and permissions. Then push a trivial change to a sibling repository’s main branch and verify that robot-code’s integration workflow triggers; done means the secret works and the dispatch occurs.
