feat: route SMS to primary agents

[xnoto]

Summary

Routes the signed Twilio SMS/MMS bridge to the existing primary OpenCode agents (lawnmowerman, grillmaster, homesteader, and homerepair) rather than the isolated *-sms profiles. The routing parser still accepts exactly four fixed destination mappings and now rejects the legacy aliases. The approved-source, signed-webhook, account, destination, media, session, and caller-controlled-routing boundaries are unchanged.

Fixes: None — implements the owner-approved full-capability primary-agent SMS design.

Type of change

• Feature / enhancement
• Container image
• Breaking change

Validation

• Required pull-request checks pass — buildah run 33809417552 passed, including the image build.
• Generated or centrally distributed files were regenerated by their owning automation, not hand-edited — not applicable.

Impact and rollout

images is the producer. On an explicitly approved merge, main publishes ghcr.io/makeitworkcloud/opencode-sms-bridge tagged with the immutable merge SHA. The separately authored charts PR #77 documents compatible chart 0.1.1 and has passing checks.

Neither artifact is selected by GitOps today. A later focused kustomize-cluster PR must select the exact published image SHA and chart revision together, configure only the approved source number(s) in the encrypted routing Secret, then separately verify reconciliation, health, and representative messaging. This PR does not configure Twilio, deploy, or alter the running OpenCode service.

Rollback is a future GitOps selection of a compatible prior immutable image and routing configuration; no live change occurs 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 intentional expansion to existing primary-agent permissions and MCP availability carefully.
