Complete the stop reason propagation chain so ACP clients can
distinguish end_turn from max_tokens:
- server-chat.ts: emitChatFinal accepts optional stopReason param,
includes it in the final payload, reads it from lifecycle event data
- translator.ts: read stopReason from the final payload instead of
hardcoding end_turn
Chain: LLM API → run.ts (meta.stopReason) → agent.ts (lifecycle event)
→ server-chat.ts (final payload) → ACP translator (PromptResponse)
* fix(gateway): flush throttled delta before emitChatFinal
The 150ms throttle in emitChatDelta can suppress the last text chunk
before emitChatFinal fires, causing streaming clients (e.g. ACP) to
receive truncated responses. The final event carries the complete text,
but clients that build responses incrementally from deltas miss the
tail end.
Flush one last unthrottled delta with the complete buffered text
immediately before sending the final event. This ensures all streaming
consumers have the full response without needing to reconcile deltas
against the final payload.
* fix(gateway): avoid duplicate delta flush when buffer unchanged
Track the text length at the time of the last broadcast. The flush in
emitChatFinal now only sends a delta if the buffer has grown since the
last broadcast, preventing duplicate sends when the final delta passed
the 150ms throttle and was already broadcast.
* fix(gateway): honor heartbeat suppression in final delta flush
* test(gateway): add final delta flush and dedupe coverage
* fix(gateway): skip final flush for silent lead fragments
* docs(changelog): note gateway final-delta flush fix credits

## Overview
This PR enables external channel plugins (loaded via Plugin SDK) to access
advanced runtime features like AI response dispatching, which were previously
only available to built-in channels.
## Changes
### src/gateway/server-channels.ts
- Import PluginRuntime type
- Add optional channelRuntime parameter to ChannelManagerOptions
- Pass channelRuntime to channel startAccount calls via conditional spread
- Ensures backward compatibility (field is optional)
### src/gateway/server.impl.ts
- Import createPluginRuntime from plugins/runtime
- Create and pass channelRuntime to channel manager
### src/channels/plugins/types.adapters.ts
- Import PluginRuntime type
- Add comprehensive documentation for channelRuntime field
- Document available features, use cases, and examples
- Improve type safety (use imported PluginRuntime type vs inline import)
## Benefits
External channel plugins can now:
- Generate AI-powered responses using dispatchReplyWithBufferedBlockDispatcher
- Access routing, text processing, and session management utilities
- Use command authorization and group policy resolution
- Maintain feature parity with built-in channels
## Backward Compatibility
- channelRuntime field is optional in ChannelGatewayContext
- Conditional spread ensures it's only passed when explicitly provided
- Existing channels without channelRuntime support continue to work unchanged
- No breaking changes to channel plugin API
## Testing
- Email channel plugin successfully uses channelRuntime for AI responses
- All existing built-in channels (slack, discord, telegram, etc.) work unchanged
- Gateway loads and runs without errors when channelRuntime is provided
Take the safe, tested subset from #32367:\n- per-channel startup connect grace in health monitor\n- tool-context channel-provider fallback for message actions\n\nCo-authored-by: Munem Hashmi <munem.hashmi@gmail.com>
When controlUiBasePath is set, classifyControlUiRequest returned
method-not-allowed (405) for all non-GET/HEAD requests under basePath,
blocking plugin webhook handlers (BlueBubbles, Mattermost, etc.) from
receiving POST requests. This is a 2026.3.1 regression.
Return not-control-ui instead, matching the empty-basePath behavior, so
requests fall through to plugin HTTP handlers. Remove the now-dead
method-not-allowed type variant, handler branch, and utility function.

* fix(types): resolve pre-existing TS errors in agent-components and pairing-store
- agent-components.ts: normalizeDiscordAllowList returns {allowAll, ids, names},
not an array — use ids.values().next().value instead of [0] indexing
- pairing-store.ts: add non-null assertions for stat after cache-miss guard
(resolveAllowFromReadCacheOrMissing returns early when stat is null)

* fix(webchat): suppress NO_REPLY token in chat transcript rendering
Filter assistant NO_REPLY-only entries from chat.history responses at
the gateway API boundary and add client-side defense-in-depth guards in
the UI chat controller so internal silent tokens never render as visible
chat bubbles.
Two-layer fix:
1. Gateway: extractAssistantTextForSilentCheck + isSilentReplyText
filter in sanitizeChatHistoryMessages (entry.text takes precedence
over entry.content to avoid dropping messages with real text)
2. UI: isAssistantSilentReply + isSilentReplyStream guards on all 5
message insertion points in handleChatEvent and loadChatHistory
Fixes#32015

* fix(webchat): align isAssistantSilentReply text/content precedence with gateway
* webchat: tighten NO_REPLY transcript and delta filtering

The health monitor was created once at startup and never touched by
applyHotReload(), so changing channelHealthCheckMinutes only took
effect after a full gateway restart.
Wire up a "restart-health-monitor" reload action so hot-reload can
stop the old monitor and (re)create one with the updated interval —
or disable it entirely when set to 0.
Closes#32105

* fix(gateway): move plugin HTTP routes before Control UI SPA catch-all
The Control UI handler (`handleControlUiHttpRequest`) acts as an SPA
catch-all that matches every path, returning HTML for GET requests and
405 for other methods. Because it ran before `handlePluginRequest` in
the request chain, any plugin HTTP route that did not live under
`/plugins` or `/api` was unreachable — shadowed by the catch-all.
Reorder the handlers so plugin routes are evaluated first. Core
built-in routes (hooks, tools, Slack, Canvas, etc.) still take
precedence because they are checked even earlier in the chain.
Unmatched plugin paths continue to fall through to Control UI as before.
Closes#31766
* fix: add changelog for plugin route precedence landing (#31885) (thanks @Sid-Qin)
