Closes #35

Why this change

Fix character avatar crops so the library and panel render the stored crop region consistently.

What changed

• Added a shared CharacterAvatarImage helper in the React character feature.
• Swapped the character library and panel avatar renders to use the shared crop-aware image path.
• Kept crop parsing and style application inside the character UI layer.

Validation

• pnpm typecheck
• pnpm build
• cargo check --manifest-path src-tauri/Cargo.toml
• pnpm check:docs when docs, skills, or repo guidance changed
• Ran pnpm tauri dev and tested the app path manually
• Verified the affected feature in the right mode(s): chat, roleplay, game, settings/providers, imports/exports, or assets

Manual verification notes

• Not run.

Docs impact

• No docs changes needed
• Updated docs/developer/* or repo guidance as needed
