Refactor main.go to reduce cyclomatic complexity

Breaks down large functions into smaller, focused helpers to pass gocyclo linter: Auto-import refactoring: - Extract parseJSONLIssues() to handle JSONL parsing - Extract handleCollisions() to detect and report conflicts - Extract importIssueData() to coordinate issue/dep/label imports - Extract updateExistingIssue() and createNewIssue() for clarity - Extract importDependencies() and importLabels() for modularity Flush refactoring: - Extract recordFlushFailure() and recordFlushSuccess() for state management - Extract readExistingJSONL() to isolate file reading logic - Extract fetchDirtyIssuesFromDB() to separate DB access - Extract writeIssuesToJSONL() to handle atomic writes Command improvements: - Extract executeLabelCommand() to eliminate duplication in label.go - Extract addLabelsToIssue() helper for label management - Replace deprecated strings.Title with manual capitalization Configuration: - Add gocyclo exception for test files in .golangci.yml All tests passing, no functionality changes.
