Add gantt chart for task visibility

[ethanrous]

Added gantt chart for task history observability on the dev page in the settings

[Copilot]

Pull request overview

Adds a task-history Gantt chart to the Settings → Dev page for improved task observability, backed by expanded task API data (timing/metadata/error) and incremental polling support.

Changes:

• Introduces a new Gantt chart UI (chart, axis, bars, tooltip) and a useTaskHistory composable to accumulate polled task history.
• Extends /tower/tasks to optionally include exited tasks and filter exited results by a since epoch-ms cursor.
• Expands TaskInfo across backend + generated clients/docs to include queue/finish timestamps, metadata, and error text.

models/task/worker_pool.go:555

• Finished non-persistent tasks are now retained indefinitely in WorkerPool.taskMap. This changes the documented semantics of Options.Persistent (which says non-persistent tasks are removed) and can lead to unbounded memory growth and slower scans over GetTasks() (e.g., services/embed/embed_service.go iterates all tasks). Consider adding a bounded retention policy (TTL / max count) for exited tasks, or restoring eviction for non-persistent tasks while separately tracking recent history for observability.

					directParent.IncCompletedTasks(1)

					// Run cleanup routines for the task

models/task/worker_pool.go:556

• Finished tasks are no longer removed from wp.taskMap, so the worker pool will retain every task ever dispatched for the lifetime of the process. Without a retention policy (max age / max count / explicit cleanup) this can grow unbounded and increase memory usage and response sizes over time (even with the new since cursor, the server still stores everything).

					// Update parent task pools about completed task
					directParent := t.GetTaskPool()
					directParent.IncCompletedTasks(1)

					// Run cleanup routines for the task
					wp.cleanupTask(t, workerID)

models/task/worker_pool.go:556

• Finished tasks are no longer removed from the worker pool’s taskMap (the previous cleanup path was removed), so taskMap will grow unbounded over the server lifetime. This has clear memory/operational risk, and also makes the initial includeExited=true&since=0 poll potentially huge.

					// Wake any waiters on this task
					close(t.waitChan)

					// Potentially find the task pool that houses this task pool. All child
					// task pools report their status to the root task pool as well.
					// Do not use any global pool as the root
					rootTaskPool := t.taskPool.GetRootPool()

					if t.exitStatus.Load() == TaskError && !rootTaskPool.IsGlobal() {
						rootTaskPool.AddError(t)
					}

					// Update parent task pools about completed task
					directParent := t.GetTaskPool()
					directParent.IncCompletedTasks(1)

					// Run cleanup routines for the task
					wp.cleanupTask(t, workerID)
