Update agent config based on PR review feedback

/kind cleanup

What this PR does / why we need it:

Updates agent configuration files based on actionable patterns identified from recent PR review feedback. Three conventions are added:

1. Always update self-development configs and examples when adding new API fields/features — Reviewers repeatedly asked agents to update self-development/ and examples/ when introducing new fields (PR Add spec.on as alias for spec.when on TaskSpawner #720, PR Add per-source pollInterval override #719).
2. Do not hard-code future API version names in deprecation notices — Reviewer noted that the next API version is not yet determined, so agents should not write things like "will be removed in v1alpha2" (PR Add spec.on as alias for spec.when on TaskSpawner #720).
3. /kind <label> in PR body auto-applies the label — Reviewer pointed out that including /kind something in the body already handles label application, making --label kind/... flags redundant (PR Remove redundant git checkout from pr-responder setup #705). Fixed the kelos-image-update prompt which was using the redundant flag.
