The PR is not ready to merge because the earlier tracing startup bug remains open.

Findings

1.  enable from environment runs once when code revision is imported. Normal worker startup imports register agent before EnvironmentVariables.refresh loads supported .env and .env.local files. A valid AGENT COMMIT SHA from those files reaches registration but never enables tracing. Run the hook after refresh, or read the value lazily. ▶

Fix with agent prompt

### Issue 1
src/agentex/lib/core/tracing/code_revision.py:undefined-124
`_enable_from_environment()` runs once when `code_revision` is imported. Normal worker startup imports `register_agent` before `EnvironmentVariables.refresh()` loads supported `.env` and `.env.local` files. A valid `AGENT_COMMIT_SHA` from those files reaches registration but never enables tracing. Run the hook after refresh, or read the value lazily.

Summary

This release makes agent deployments carry their image version and source details automatically. It also publishes version 0.27.0 for both packages and records the included changes in each changelog.

• Helm deployments now derive the agent version from the final image tag.
• Tracing and registration can report the agent's commit and source repository.
• Both packages move from 0.26.0 to 0.27.0.
