Bug Report

Feature Area: TUI — Throbber / Loading States

Severity: Medium (visual feedback missing)

What Was Tested

The TUI throbber as defined in the specification (§ Throbber, §Loading States).

Expected Behavior (from spec)

A rainbow gradient animated bar spans the full width at the top of the screen, visible only when the actor is processing. It collapses to zero height when idle.

The gradient cycles through 12 colors at 15fps:
#881177 → #aa3355 → #cc6666 → #ee9944 → #eedd00 → #99dd55 → #44dd88 → #22ccbb → #00bbcc → #0099cc → #3366bb → #663399

The spec also defines an alternative quotes style (ui.throbber: quotes) that displays shuffled quotes from a ~200-entry collection, rotating every 3 seconds. Example quotes:

"I'm sorry, Dave. I'm afraid I can't do that." — HAL 9000
"Any sufficiently advanced technology is indistinguishable from magic." — Arthur C. Clarke

Both styles occupy 1 row at the top and collapse to zero height when idle.

Actual Behavior (from code analysis)

The CleverAgentsTuiApp.compose() in src/cleveragents/tui/app.py yields a standard Textual _Header(show_clock=True) widget (line 110). There is no throbber widget, no rainbow gradient, no quotes display, and no collapse-to-zero-height behavior.

No throbber widget file exists anywhere in src/cleveragents/tui/.

Steps to Reproduce

Run agents tui
Observe the top of the screen shows a standard Textual header with clock
No rainbow gradient bar appears even when the actor is processing

Code Location

src/cleveragents/tui/app.py line 110 (yield _Header(show_clock=True))
No throbber widget exists in src/cleveragents/tui/widgets/

Impact

Users have no visual indication that the actor is processing. The rainbow throbber is a key UX element that distinguishes the TUI from a static terminal.
