**[SONAR
DASHBOARD](https://sonarcloud.io/project/overview?id=ankitects_anki)**

Integrates SonarCloud into the CI pipeline as a proof of concept to
evaluate whether
it surfaces actionable quality and security insights for this codebase.

Changes:
- Added `sonar-project.properties` configuring sources (`pylib`, `qt`,
`ts`, `rslib`)
  and coverage report paths
- Extended `tools/coverage/coverage-py` (and `.bat`) to emit
`coverage.xml` (Cobertura)
- Extended `tools/coverage/coverage-ts` (and `.bat`) to emit `lcov.info`
via the V8 provider
- Extended `tools/coverage/coverage-rust` (and `.bat`) to emit
`lcov.info` via
  `cargo-llvm-cov report`
- Added a `SonarCloud Scan` step to the `check-linux` CI job, running
after all
  checks pass and before the build cache is saved

## How to test

### Details

**1. Install sonar-scanner**
```bash
brew install sonar-scanner
```

**2. Generate and configure a token**

Go to [sonarcloud.io](https://sonarcloud.io/) → My Account → Security →
Generate Token
Copy the generated token and export it in your shell:
```
export SONAR_TOKEN=your_token_here
```

**3. Generate coverage reports**
```
just test --coverage
```
Expected output files:

 - out/coverage/python-pylib/coverage.xml
 - out/coverage/python-qt/coverage.xml
 - out/coverage/typescript/lcov.info
 - out/coverage/rust/lcov.info

**4. Run the scanner manually**
```
sonar-scanner
```
Results will appear in the SonarCloud dashboard

To test coverage generation locally:
```bash
just coverage
# verify files exist:
# out/coverage/python-pylib/coverage.xml
# out/coverage/python-qt/coverage.xml
# out/coverage/typescript/lcov.info
# out/coverage/rust/lcov.info
```
