User Story

As a loom-tui user, I want to press a in the LoRA panel to open a searchable overlay listing all available LoRAs from the backend, so that I can browse, search, and add LoRAs to my generation without memorizing filenames.

Context

The Generate screen LoRA panel (#21) supports add/remove/adjust operations, but a currently has no backend data source. This overlay connects to PluginBridge to fetch the available LoRA list and renders a picker with preview images.

Acceptance Criteria

Overlay

a in the LoRA panel opens a floating overlay listing all LoRAs from the active backend
Fuzzy search filters the list in real-time (reuse nucleo_matcher from command palette)
Each LoRA entry shows: name, base model compatibility, file size
Preview images rendered via ImageRenderer (if available from backend)
Enter adds the selected LoRA to the Generate screen's LoRA list with default weight 1.0
Esc closes without adding
Already-added LoRAs are visually marked (dimmed or tagged)

Data

LoRA list fetched from PluginBridge (cached per session, refreshable with Ctrl+R)
Loading spinner shown while fetching

Tests

Unit test: fuzzy filter on LoRA names
Unit test: adding a LoRA from overlay updates Generate screen state

Out of Scope

LoRA downloading/installation (that's Model browser territory)
LoRA weight editing (already implemented in LoRA panel)

References

Spec §4.1.2 ("LoRA list: a to add a LoRA opens LoRA browser overlay")
Existing code: src/screens/generate.rs (LoRA panel), src/components/palette.rs (fuzzy search pattern)
