chat.agent Improvements

• Reliability fixes for chat.agent. A user message sent while the agent is streaming is no longer delivered twice (which could run a duplicate turn), input appends now carry an idempotency key so a retried send can't duplicate a message, stopping a generation clears the streaming state so a page reload doesn't replay the stopped turn, and runs can now carry the full set of dashboard tags instead of being silently truncated. onTurnComplete now fires on errored turns (with the thrown error attached) and the failed turn's user message is persisted so it isn't lost on the next run. Custom agents and manual chat.writeTurnComplete callers now trim the output stream, sending a custom action no longer leaves a second stream reader running, and a long-lived watch subscription no longer grows its dedupe set without bound. (#3891)
• Continuation chat boots no longer stall for around 10 seconds before the first turn. The session.in resume cursor is now found with a non-blocking records read instead of draining an SSE long-poll (which always waited out its full 5 second inactivity window, twice per boot), the boot reads run concurrently, and chat snapshots carry the cursor so subsequent boots skip the scan entirely. (#3907)
• Fix two chat.createSession() bugs: stopping a generation no longer wedges the run (the turn loop raced a totalUsage promise that never settles after a stop-abort), and continuation runs now wait for the next message instead of invoking the model with an empty prompt. (#3920)

Other improvements and fixes

• trigger init now sets up your AI coding assistant as part of project setup: pick the MCP server, the agent skills, or both, then scaffold with the CLI or hand off to your assistant. Adds a new getting-started agent skill that teaches assistants how to bootstrap Trigger.dev (install the SDK, write trigger.config.ts, create a first task, run trigger dev), so the AI-driven setup path works end to end. It ships in the CLI alongside the existing skills, version-matched to your SDK. (#3872)
• dev and deploy now fail with a clear error when two tasks are defined with the same id, including across different task types (e.g. a scheduled task and a regular task sharing an id). Previously the second definition silently overwrote the first, so one of the tasks would vanish with no warning. Task ids are detected as duplicates during indexing (naming each offending id and the files it was found in), and the same rule is enforced server-side when the background worker is registered. (#3865)
• trigger skills installs Trigger.dev agent skills into your coding agent so it knows how to write tasks, schedules, realtime, and chat.agent code. The skills ship with the CLI and are copied into each tool's native skills directory (Claude Code, Cursor, GitHub Copilot, and Codex / AGENTS.md), and trigger dev offers to install them on first run. (#3868)
