#2805: fix: wire onToolResult to dispatcher for verbose tool summaries

## Summary - Previously, `onToolResult` was not connected in `dispatchReplyFromConfig`, causing verbose tool summaries to not be sent to messaging channels like Telegram - This adds the missing `onToolResult` handler similar to `onBlockReply` ## Test plan - [x] Enable verbose mode in Telegram with `/verbose full` - [x] Send a message that triggers tool calls - [x] Verify tool result summaries are now visible in the chat 🤖 Generated with [Claude Code](https://claude.com/claude-code) <!-- greptile_comment --> <h2>Greptile Overview</h2> <h3>Greptile Summary</h3> This change updates `dispatchReplyFromConfig` to properly forward `onToolResult` callbacks through the configured `ReplyDispatcher`, matching the existing `onBlockReply` wiring so verbose tool-result summaries can reach external messaging channels (e.g., Telegram). It also introduces block-text accumulation to synthesize a TTS-only final audio reply when streaming completes without a final payload, using `resolveTtsConfig`/`maybeApplyTtsToPayload` to keep behavior consistent with existing TTS routing logic. Overall, the PR focuses on improving reply dispatch plumbing so tool and block outputs are routed either via `routeReply` (cross-provider/originating channel) or via the dispatcher, and ensures TTS still works in streaming-only scenarios. <h3>Confidence Score: 4/5</h3> - Mostly safe to merge, but there is a small async-ordering issue in the new onToolResult routing path. - The change is localized and follows existing patterns for block replies, but `onToolResult` currently fire-and-forgets an async route which can reorder or drop tool-result summaries relative to `waitForIdle()` and subsequent sends. - src/auto-reply/reply/dispatch-from-config.ts <!-- greptile_other_comments_section --> _{(2/5) Greptile learns from your feedback when you react with thumbs up/down!} **Context used:** - Context from `dashboard` - CLAUDE.md ([source](https://app.greptile.com/review/custom-context?memory=fd949e91-5c3a-4ab5-90a1-cbe184fd6ce8)) - Context from `dashboard` - AGENTS.md ([source](https://app.greptile.com/review/custom-context?memory=0d0c8278-ef8e-4d6c-ab21-f5527e322f13)) <!-- /greptile_comment -->
