feat: add CI with osquery integration tests and coverage

# Summary

Complete CI infrastructure refactor with osquery integration testing and coverage measurement.

## Changes

### CI Workflow (`.github/workflows/ci.yml`)
- Renamed workflow from "Rust CI" to "CI"
- Split into build (fmt, clippy, build) and test jobs
- Added osquery installation for integration tests
- Integrated `cargo-llvm-cov` for coverage measurement
- Added dynamic coverage badge via Gist

### Test Script (`scripts/ci-test.sh`)
- New orchestration script for local and CI testing
- Detects osqueryd (PATH and common install locations)
- Falls back to Docker when osqueryd not available
- Builds and autoloads logger-file and config-static extensions
- Waits for socket AND extension registration before tests
- Generates lcov coverage reports with `--coverage` flag
- Cross-platform cleanup using `pkill -f` pattern matching

### Docker Support
- Added `docker/Dockerfile.test` for containerized testing
- Pre-builds extensions in image for faster test runs
- Mirrors native test environment for consistency

### README Badge Fixes
- Fixed CI badge URL (workflows/CI not workflows/Rust%20CI)
- Fixed coverage link (ci.yml not coverage.yml)

## Testing

- 161 tests passing
- ~87% code coverage
- CI completes in ~1.5 minutes
