chore(kiloclaw): update OpenClaw to 2026.4.23

[joshavant]

Summary

• Updates the bundled KiloClaw OpenClaw version from 2026.4.15 to 2026.4.23 and aligns the Kilo Chat plugin peer dependency.
• Adds the hook session-key prefix migration required by OpenClaw 2026.4.23 so existing KiloClaw instances with inbound-email hooks can start safely after upgrading.
• Updates version fixtures, examples, and the KiloClaw changelog entry for the new OpenClaw version.

Verification

• Deployed a dev KiloClaw instance and confirmed the controller and gateway reached ready after startup.
• Confirmed the expected startup connection-refused logs stop once OpenClaw finishes binding the gateway port.

Reviewer Notes

• This is stacked on chore(kiloclaw): update runtime dependencies #3002 and should be reviewed against chore/update-kiloclaw-runtime-deps.
• OpenClaw 2026.4.23 tightened hook config validation; without the new hooks.allowedSessionKeyPrefixes patch, existing instances with templated hook session keys can fail gateway startup.
• First boot remains slow while openclaw onboard runs and bundled plugin deps are repaired; the controller can emit transient ECONNREFUSED 127.0.0.1:3001 logs until the gateway is ready.
