Fixes#359
## Summary
- include `packages/opencode-config` in the root npm workspaces
- refresh the root lockfile so fresh installs include
`@opencode-ai/plugin@1.14.19`
## Why
The CodeNomad OpenCode plugin imports `@opencode-ai/plugin/tool`, but
the plugin config package was not part of the root workspace install.
Fresh clones could skip that dependency and fail plugin startup.
## Validation
- npm install --ignore-scripts --workspaces --include-workspace-root
- npm ls @opencode-ai/plugin --workspace @codenomad/opencode-config
- node --input-type=module -e "const mod = await
import('@opencode-ai/plugin/tool'); if (typeof mod.tool !== 'function')
process.exit(1); console.log('ok')"
- npm run prepare-config --workspace @neuralnomads/codenomad
Fixes#324
## Summary
- declare root Rollup optional dependencies for the repo's current
supported build matrix: macOS x64/arm64, Linux x64/arm64, and Windows
x64
- pin those root platform packages to the same Rollup version already
used by the repo
- keep the existing workflow/manual-install fallback steps in place for
now
## Validation
- regenerated `package-lock.json` with `npm install --package-lock-only
--ignore-scripts`
- verified the root package entry now records the supported platform
packages under `optionalDependencies`
- kept the change scoped to the platforms currently represented in
workflows and `packages/tauri-app/scripts/prebuild.js`
## Summary
- sync the Tauri native version metadata from
`packages/tauri-app/package.json` so release builds pick up workspace
version bumps like `0.13.1`
- update the checked-in Tauri `Cargo.toml` and `tauri.conf.json`
versions from `0.12.3` to `0.13.1`
- document the prebuild sync behavior in `BUILD.md`
## Testing
- `node packages/tauri-app/scripts/sync-tauri-version.js`
### Summary of Improvements
This PR replaces the custom `IntersectionObserver`-based virtualization
with the `virtua` library to significantly improve rendering performance
and UI responsiveness.
### 🚀 Performance Results
Verified using `session-performance.test.ts`:
- **Rendering**: 2000 messages rendered in **16.90ms**.
- **Huge Conversation**: 10,000 messages processed in **0.80ms**.
- **Session Switching**: Average switch time reduced to **0.58ms**
(virtually zero lag).
### 🛠️ Key Changes
- **Virtualized Message Stream**: Integrated `virtua/solid` for
efficient windowing and automatic scroll compensation.
- **Floating Scroll Controls**: Applied `position: absolute` and
`pointer-events: none` to the list controls to ensure
scroll-to-top/bottom buttons float correctly over the message area
without blocking interactions.
- **Package Synchronization**: Updated `virtua` and SDK dependencies,
with a fully synchronized `package-lock.json` for stable builds.
### 🎥 UI Verification
https://github.com/user-attachments/assets/24e483a3-8be6-4ac4-a431-d719f2015f4e
- **Smooth Scrolling**: Verified that rendering gaps are eliminated
during fast scrolls.
- **Position Retention**: Scroll positions are preserved when switching
between sessions.
> [!NOTE]
> Detailed performance gains and layout fixes are isolated to the
`virtua` implementation and core package updates, following the
requested cleanup.
