- Doctor/Telegram: warn when selected Telegram quote replies can suppress `streaming.preview.toolProgress`, and document the `replyToMode` trade-off without changing runtime delivery. Fixes #73487. Thanks @GodsBoy.

- Channels/Discord: send a best-effort native typing cue immediately after an inbound DM is accepted, so slow pre-dispatch turns show Discord liveness before queueing, context assembly, model, or tool work starts. Fixes #76417. Thanks @mlopez14.

- Plugins/install: reject source-only TypeScript package installs and installed plugin packages that are missing compiled runtime output, so broken npm artifacts fail at install/discovery time instead of falling through jiti and surfacing later as unavailable providers. Fixes #76720.

- Plugins/config: deduplicate identical manifest compatibility diagnostics when an explicitly configured plugin overrides another discovered candidate, so external channel plugins do not print the same missing `channelConfigs` warning repeatedly during install and enable. Thanks @vincentkoc.

- Discord/status: honor explicit `messages.statusReactions.enabled: true` in tool-only guild channels so queued ack reactions can progress through thinking/done lifecycle reactions instead of stopping at the initial emoji. Thanks @Marvinthebored.

- Discord/native commands: compare Discord-normalized slash-command descriptions and localized descriptions during reconcile so CJK or multiline command text no longer triggers redundant startup PATCH bursts and rate-limit 429s. Fixes #76587. Thanks @zhengsx.

- Agents/OpenAI: omit Chat Completions `reasoning_effort` for `gpt-5.4-mini` only when function tools are present while preserving tool-free Chat and Responses reasoning support, preventing Telegram-routed fallback runs from hanging after OpenAI rejects tool payloads. Fixes #76176. Thanks @ThisIsAdilah and @chinar-amrutkar.
