### Fixes

- Exec: reject invalid per-call `host` values instead of silently falling back to the default target, so hostname-like values fail before commands run. Fixes #74426. Thanks @scr00ge-00 and @vyctorbrzezowski.

- Google/Gemini: send non-empty placeholder content when a Gemini run is triggered with empty or filtered user content, avoiding `contents is not specified` API errors. Thanks @CaoYuhaoCarl.

- Build/Gateway: route restart, shutdown, respawn, diagnostics, command-queue cleanup, and runtime cleanup through one stable gateway lifecycle runtime entry so rebuilt packages do not strand long-running gateways on stale hashed chunks. Carries forward #73964. Thanks @pashpashpash.

- Memory/wiki: keep broad shared-source and generated related-link blocks from turning every page into a search hit, cap noisy backlinks, support all-term searches such as people-routing queries, and prefer readable page body snippets over generated metadata. Thanks @vincentkoc.

- Cron/Gateway: abort and bounded-clean up timed-out isolated agent turns before recording the timeout, so stale cron sessions cannot leave Discord or other chat lanes stuck in `processing` after a timeout. Thanks @vincentkoc.
