Pin init images with span-level message-id tracing

[casey-brooks]

Summary

agynio/agents-orchestrator#207 remains red only on Claude/Codex full-chain tracing deeplink after expose lifecycle was fixed and agent-init-codex:0.13.28 / agent-init-claude:0.1.28 were pinned.

Latest validation run: https://github.com/agynio/agents-orchestrator/actions/runs/26902699431

Confirmed in that run:

• TestAgentExposeLifecycle_ListAddRemove passes.
• Claude/Codex still fail with ListSpans(filter: { messageId }) returned no trace id after 120s.

Fix path

• fix(tracing): mirror message id on spans agynd-cli#136 released agynd v0.14.18, which mirrors agyn.thread.message.id onto exported span attributes while preserving resource-level injection.
• chore(versions): bump agynd to 0.14.18 agyn-runtime-codex#59 published ghcr.io/agynio/agent-init-codex:0.13.29 with AGYND_VERSION=0.14.18.
• chore(versions): bump agynd to 0.14.18 agyn-runtime-claude#48 published ghcr.io/agynio/agent-init-claude:0.1.29 with AGYND_VERSION=0.14.18.

Required change

Pin centralized E2E defaults from:

• agent-init-codex:0.13.28 -> agent-init-codex:0.13.29
• agent-init-claude:0.1.28 -> agent-init-claude:0.1.29

No skips.
