- Agents/output: drop copied inbound metadata-only assistant replay turns before provider replay instead of synthesizing a placeholder, so Telegram and other channels cannot receive `[assistant copied inbound metadata omitted]` as model output. Fixes #74745. Thanks @adamwdear and @Marvae.

- Doctor/memory: suppress skipped embedding-readiness warnings for key-optional providers such as Ollama and LM Studio while preserving timeout and not-ready diagnostics. Fixes #74608 and #73882. Thanks @hclsys.

- Channels/groups: preserve observe-only turn suppression for prepared dispatch paths and restore deprecated channel turn runtime aliases, so passive observer/group flows stay silent while older plugins keep compiling. Thanks @vincentkoc.

- Feishu: skip empty-text messages (e.g. `{"text":""}`) that carry no media, so no blank user turn is written to the session and downstream LLM providers cannot reject the request with "messages must not be empty". (#74634) Thanks @xdengli and @hclsys.

- Feishu/Bitable: clean up newly created placeholder rows whose fields contain only default empty values while preserving meaningful link, attachment, user, number, boolean, and location values during create-app cleanup. (#73920) Carries forward #40602. Thanks @boat2moon.

- macOS app: keep attach-only mode and the Debug Settings launchd toggle marker-only, so launching with `--attach-only`/`--no-launchd` no longer uninstalls the Gateway LaunchAgent or drops active sessions. (#72174) Thanks @DolencLuka.

- Plugin SDK: restore the deprecated `plugin-sdk/zalouser` command-auth facade so published Lark/Zalo plugins that import it load on current hosts. Fixes #74702. Thanks @Goron01.
