User story

As a user on the Generate screen, I want to add, remove, and tune LoRA weights before kicking off a generation, so that I can layer styles and characters on top of the base model.

Acceptance criteria

Scrollable list below the parameter bar (per §4.1.1 layout)
Each row: name, weight (f32, editable inline), remove hint
j/k move selection; a opens the LoRA browser overlay; d removes the focused row; +/- adjusts weight by 0.05; typing digits edits weight directly

LoRA browser overlay

Populated from loom-core installed LoRAs (PluginBridge::list_loras())
Supports fuzzy search by name
Enter adds the selected LoRA to the list with default weight 1.0
Esc closes without changes

Integration

LoRA weights are serialised into the generation params passed to the backend
Removing a LoRA updates the in-memory params and triggers a re-render
Weight range validated [-2.0, 2.0]

Tests

Unit test: adding the same LoRA twice replaces the existing row instead of duplicating it
Unit test: weight adjustment clamps at ±2.0

Out of scope

Installing new LoRAs from CivitAI / HF (Model Browser ticket)
ControlNet panel (separate mode-tabs ticket)
