Bug Report

Feature Area: TUI — Multiline Prompt Detection

What Was Tested

The spec (§ "Prompt Architecture Detail — Multiline Detection") defines auto-detection of multiline input with mode switching.

Expected Behavior (from spec)

The prompt auto-detects multiline input and switches the prompt symbol to ☰:

Condition	Result
Input contains `\n` (newline character)	Switch to multiline mode
Input contains triple backticks (```)	Switch to multiline mode
`shift+enter` or `ctrl+j` pressed	Insert newline, switch to multiline
All newlines removed	Revert to single-line mode

In multiline mode, enter inserts a newline; ctrl+enter submits. In single-line mode, enter submits.

The prompt symbol changes: ❯ (normal), $ (shell), ☰ (multiline).

Actual Behavior

The PromptInput widget in src/cleveragents/tui/widgets/prompt.py is a thin wrapper around Textual's Input widget. It has no multiline detection, no mode switching, no shift+enter/ctrl+j handlers, and no prompt symbol changes.

The InputModeRouter in src/cleveragents/tui/input/modes.py only detects / (command) and ! (shell) prefixes — it has no multiline detection.

Code Location

src/cleveragents/tui/widgets/prompt.py — no multiline detection
src/cleveragents/tui/input/modes.py — no multiline mode
Spec reference: §"Multiline Detection" (line ~30035 in docs/specification.md)

Impact

Users cannot compose multi-line prompts (e.g., code snippets, structured requests) in the TUI. The shift+enter shortcut for inserting newlines is non-functional.
