Tasks: UI download chat logs (nice-to-have)

[mafredri]

Repo: coder/coder

Scope: Add "Download chat logs" option to task list kebab menu. This is a nice-to-have feature that can be deferred if GA schedule is tight.

Design notes:

• Appears in task row kebab (3-dot) menu alongside "Share workspace" and "Delete task"
• Downloads conversation history using existing logs endpoint response format
• Filename: {task-name}-logs.json

Changes:

• Add "Download chat logs" menu item to task row actions
• Call existing GET /tasks/{user}/{task}/logs endpoint
• Save response as JSON file (same format the endpoint returns)

Files:

• site/src/pages/TasksPage/TasksTable.tsx

Acceptance criteria:

• "Download chat logs" appears in task row menu
• Downloads logs for both active and paused tasks
• Uses existing logs endpoint response format (no transformation)
• Filename includes task name

Dependencies:

• Tasks: Return log snapshot from logs endpoint when paused #1254
