Add API report regeneration command to ai-integrations workspace AGENTS.md

What happened

On PR #3742 (https://github.com/redhat-developer/rhdh-plugins/pull/3742), the code agent's initial commit added new public exports (AIResourceScopeValidator, VALID_AI_RESOURCE_SCOPES, AIResourceScope type) to the catalog-backend-module-ai-resource-extensions plugin but did not regenerate report.api.md. CI failed on the api-reports check. The human triggered '/fs-fix Fix the failing API reports error on the CI check' at 20:52 UTC on July 13 (fix iteration 2, ~13 min to resolve). Later, after the human pushed a rename commit at 19:01 UTC on July 14, the api-report needed regeneration again, requiring fix iteration 4 (~13 min). The workspace AGENTS.md at workspaces/ai-integrations/AGENTS.md lists build, test, lint, and type-check commands but does not mention 'yarn build:api-reports'. The repo's CONTRIBUTING.md (lines 316-325) documents this as mandatory for API changes, but that file is not in the agent's primary instruction path.

What could go better

If the workspace AGENTS.md included 'yarn build:api-reports' in the Build & Test Commands section, both the code agent and fix agent would have clear guidance to regenerate API reports after modifying public exports. This would have prevented fix iterations 2 and 4 entirely, saving ~26 minutes of agent compute time and eliminating 2 of the 4 human-triggered fix requests. Confidence is high that documenting the command would help — the code agent already successfully follows other commands listed in the same AGENTS.md (e.g., it ran tests). Uncertainty: the code agent may not run all listed commands before submitting (see fullsend-ai/fullsend#1719 for the platform-level issue), but having the command documented is a necessary prerequisite for it to be run. Issue #3745 in this repo covers adding changeset instructions to .fullsend/AGENTS.md but does not cover adding api-report regeneration to the workspace-level AGENTS.md.

Proposed change

Add 'yarn build:api-reports' to the Build & Test Commands section in workspaces/ai-integrations/AGENTS.md. Also add a 'CI Requirements' subsection with guidance: 'When adding or modifying public exports in index.ts, run yarn build:api-reports from the workspace root and commit the updated report.api.md files. This is a required CI check that will fail if reports are stale.' Example addition to the commands list: '- API reports: yarn build:api-reports (run after modifying public exports)'.

Validation criteria

On the next agent-authored PR in the ai-integrations workspace that adds or modifies public API exports: the code agent includes an updated report.api.md in its initial commit without requiring a human-triggered /fs-fix, OR the fix agent addresses the failing api-reports check autonomously using the documented command without requiring the human to diagnose the problem.

Generated by retro agent from https://github.com/redhat-developer/rhdh-plugins/pull/3742

Update workspaces/ai-integrations/AGENTS.md in the Build & Test Commands section. Document yarn build:api-reports and add the stated CI guidance for public exports in index.ts, including committing updated report.api.md files. Verify that the command and required behavior are clearly described.
