docs: route SMS bridge to primary agents

[xnoto]

Summary

Updates the SMS bridge chart contract to route the four fixed destination numbers to the existing primary OpenCode agents: lawnmowerman, grillmaster, homesteader, and homerepair. This implements the owner decision that approved-source SMS sessions use the same agent configuration, permissions, MCPs, skills, and shared instructions as the normal agents. The chart does not select or deploy the bridge.

Fixes: None — documents the owner-approved routing boundary.

Type of change

• Documentation
• GitOps desired state (manifests, kustomize, charts, SOPS/KSOPS secrets)

Validation

• Required pull-request checks pass — helm run 33808947099 passed repository validation and packaged opencode-sms-bridge.
• Generated or centrally distributed files were regenerated by their owning automation, not hand-edited — not applicable.

Impact and rollout

The paired images change changes the bridge's validated agent allowlist. This PR releases opencode-sms-bridge 0.1.1 with matching consumer documentation only. The bridge has no current GitOps consumer selection, so merging/publishing this chart does not reconcile a workload or configure Twilio. A future focused kustomize-cluster PR must select this chart and the paired immutable image SHA together, supply the encrypted approved-sender routing secret, and independently verify reconciliation and health.

Rollback is a later consumer pin to chart 0.1.0 and a compatible prior image; no live resource changes occur from this PR.

Safety and secrets

• Contains no plaintext secrets, decrypted SOPS values, state files, kubeconfigs, tokens, or private endpoints
• No local OpenTofu init/plan/apply/destroy/import/state operations were run or claimed — plans come from pull-request checks
• Breaking or irreversible effects are described above with rollback notes

AI agent materially produced this change; review the owner-only ingress and full-agent-access boundary carefully.
