When the system hostname exceeds 63 bytes (common with Kubernetes pod
names), the @homebridge/ciao DNS label encoder throws an AssertionError
that crashes the gateway on startup.
Add truncateToDnsLabel() that safely truncates UTF-8 strings at byte
boundaries, applied to both the service instance name and hostname
before passing them to ciao.
Closes#37705
AI-assisted (built with Hermes orchestration).
Fix the bundled Bonjour gateway discovery crash-loop caused by ciao probe cancellation rejections after the Bonjour plugin migration.
The plugin entry now wires the existing rejection handler into the advertiser, and the unhandled-rejection handler registry is anchored on globalThis so staged plugin SDK module copies register into the same process-level handler set used by the host.
Verification:
- pnpm test:serial extensions/bonjour/src/advertiser.test.ts src/infra/unhandled-rejections.fatal-detection.test.ts
- OPENCLAW_LOCAL_CHECK_MODE=throttled pnpm check:changed partially completed: conflict markers plus core/core-test/extensions/extension-test typecheck passed; local lint lane hit a self-lock and was stopped.
