feat: write JSON output directly to file instead of stdout redirection

**Problem:**
The workflow was redirecting stdout to capture JSON output, but verbose logs
were contaminating the JSON, causing jq parsing errors. Previous attempts to
redirect verbose output to stderr were complex and error-prone.

**Solution:**
Implement file-based JSON output using BUSHEL_SYNC_JSON_OUTPUT_FILE environment
variable. This is simpler, more robust, and explicitly intentional.

**Changes:**
1. Added jsonOutputFile parameter to SyncConfiguration
2. Updated SyncCommand to write JSON directly to file when specified
3. Modified workflow to set BUSHEL_SYNC_JSON_OUTPUT_FILE=sync-result.json
4. Removed all stdout/stderr redirection complexity from workflow
5. Updated artifact upload to exclude sync.log (no longer created)
6. Replaced all print() calls with ConsoleOutput.print() to write to stderr
7. Added ConsoleOutput.print() as drop-in replacement for Swift's print()

**Benefits:**
- No risk of stdout contamination
- Simpler workflow configuration
- More explicit (file output is intentional, not a side effect)
- Easier to debug (JSON file vs console output separation is clear)
- All verbose logs visible in GitHub Actions console

**Testing:**
- Build succeeds
- JSON written to file when jsonOutputFile is specified
- Falls back to stdout when jsonOutputFile is not set

Fixes jq parsing error in cloudkit-sync.yml workflow.
