Summary

Twelfth PR. Replaces the Generate stub with a real screen holding a loom_core::GenerationParams and providing inline editors for every parameter. Stacks on #58. Closes charles/loom#20.

What's in

screens/generate.rs — GenerateScreen, GenerateFocus (11 fields), handle_prompt_key / handle_param_key
Prompt + negative multi-line editors with paste-on-typing, Backspace, Ctrl+U clear, Ctrl+W delete word, Enter newline
Parameter editors:
- Model / Sampler — string edit
- Steps / Width / Height — u32, digit entry + Backspace, clamped to [1,500] / [64,2048]
- CFG — f64, digit+dot + Up/Down for ±0.5 step, clamped [0,50]
- Seed — i64; R → -1 (random), L → last seed if present
- Batch size / count — shared u32 editor
Tab / Shift+Tab cycles focus across the whole field list
F5 runs validate() (non-empty prompt, w/h ≥ 64, steps ≥ 1, batch ≥ 1) and submits — for now a success emits an info notification; a failure emits a warn. Real generation wiring comes later in Phase 3 once PluginBridge is threaded through AppCtx
screens promoted to a directory

Tests (6 new, 65 total)

Default validation fails on empty prompt
Typing chars + backspace roundtrip in prompt
GenerateFocus::next round-trips back to Prompt
Seed R/L in the Seed field
Steps clamp low
Validation flips to None once a prompt is set

Out of scope

LoRA panel (#21), mode tabs (#22), inpaint canvas (#23), queue overlay (#24), preview pane (#25), AI enhance/tag (#26)
Model / Sampler combo pickers — today they're free-text; combo popups that draw from PluginBridge::list_models() / list_samplers() come when the bridge is wired through AppCtx

feat(tui): Generate screen — prompt editor & parameter fields 0fe5f63d66

First cut of the Generate screen. A GenerateScreen holds a
loom_core::GenerationParams instance and a GenerateFocus enum tracking
which field is focused. Tab/Shift-Tab cycles between prompt, negative,
model, sampler, steps, cfg, width, height, seed, batch size, and
batch count. Each parameter slot has its own inline editor:

- Strings (model, sampler) take printable chars + Backspace + Ctrl+U
- u32 fields (steps, width, height) parse digits and clamp to range
- f64 (cfg) supports digit/dot input + Up/Down for ±0.5 step
- Seed is i64 with `R` → -1 (random) and `L` → last used seed
- Batch slots use the same u32 editor

F5 runs validation (non-empty prompt, width/height ≥ 64, steps ≥ 1,
batch ≥ 1) and submits — for now submission just fires an info
notification. Real generation wiring waits for PluginBridge to be
threaded through AppCtx (later Phase 3 ticket).

screens is promoted to a directory (screens/mod.rs + screens/generate.rs).

Closes charles/loom#20
