User story

As a user, I want to switch between text-to-image, image-to-image, inpaint, and ControlNet modes on the Generate screen without navigating away, so that I can reuse prompts and parameters across modes.

Acceptance criteria

Tabs

Mode tabs [t2i] [i2i] [inpaint] [controlnet] rendered above the parameter bar
Switch with 1/2/3/4 or Ctrl+Tab / Ctrl+Shift+Tab
Current mode persists in Generate screen state across screen navigations

Per-mode parameter set

t2i: no extra fields
i2i: init image path field, denoising strength (0.0–1.0), resize mode; o opens file picker (spawns fzf if on $PATH, otherwise falls back to a built-in directory browser overlay); drag-and-drop path paste via bracketed paste
inpaint: init image path + launches Inpaint Canvas overlay (separate ticket) on Enter over the canvas button; mask inpainting strength
controlnet: sub-panel toggled with C; supports N ControlNet units (backend-dependent), each with model selector, preprocessor selector, weight, start/end step, image input

Preview hookup

In i2i / inpaint / controlnet, the init image shows in the preview pane via the image renderer
Invalid image paths raise a notification and disable submit

Tests

Unit test: switching from i2i to t2i hides the init-image field but preserves the prompt
Unit test: controlnet unit list can add and remove entries without reordering

Out of scope

The Inpaint Canvas overlay itself (separate ticket)
Preview pane rendering (separate ticket)
