[Docs] Document token analytics and task recovery

​Opened on behalf of @mrubens. Follow up by mentioning @roomote, in the web UI, or in Discord.

What changed

• document token totals, chart behavior, detail rows, exports, and missing provider metadata in Cost Analytics
• explain that stopping a task preserves resumable work while an explicit cancellation ends the current run
• state that Snowflake requires key-pair authentication and existing password- or token-based connections must rotate

The audit inspected all 37 first-parent merges on develop in the exact 24-hour window from 2026-09-09T03:00:45.879Z through 2026-09-10T03:00:45.879Z. Existing Agent Guidance, bounded monitoring, native charts, Blank slate, scheduling, and source-control provider documentation already matched shipped behavior and were left unchanged.

Why this change was made

Recent product changes added user-visible analytics data and changed task recovery and Snowflake authentication boundaries without fully updating their public workflow guidance.

Impact

Users and operators can now interpret token usage, choose between resumable stopping and permanent cancellation, and migrate Snowflake credentials correctly. Mintlify validation and broken-link checking passed. Rendered screenshots are unavailable because the local Mintlify preview returned an internal error for missing generated Next.js artifacts; no visual proof is claimed.

• apps/docs/fast-sessions.mdx:120 Stop is documented as resumable, but the Session-card control performs terminal cancellation.

_{Reviewed aa01b94}

[roomote-community]

The visible Session-card Stop control currently calls cancelTaskRunCommand with a run ID, and that path passes terminate: true to stopTaskRun. This is a terminal cancellation that shuts down the sandbox, so a later message cannot resume the stopped run as documented. Either make that control use the soft-stop path or describe Stop as terminal.
