Improve cmd/bd test coverage from 21% to 23.1% (bd-27ea)

Added comprehensive tests for:
- validate.go (parseChecks, validation results, orphaned deps, duplicates, git conflicts)
- restore.go (readIssueFromJSONL, git helpers)
- sync.go (git helpers, JSONL counting)

Progress: 21.0% → 23.1% (+2.1%)
Target: 40% (multi-session effort)
