Polish for open-source release

Major improvements to code quality, documentation, and CI:

Code Quality:
- Add golangci-lint configuration with 13 linters
- Fix unchecked error returns in export/import/init
- Refactor duplicate scanIssues code
- Add package comments for all packages
- Add const block comments for exported constants
- Configure errcheck to allow idiomatic defer patterns

Documentation:
- Add comprehensive CONTRIBUTING.md with setup, testing, and workflow
- Fix QUICKSTART.md binary name references (beads → bd)
- Correct default database path documentation

CI/CD:
- Add GitHub Actions workflow for tests and linting
- Enable race detection and coverage reporting
- Automated quality checks on all PRs

All tests passing. Lint issues reduced from 117 to 103 (remaining are
idiomatic patterns and test code). Ready for open-source release.

+# Contributing to bd
+
+Thank you for your interest in contributing to bd! This document provides guidelines and instructions for contributing.
+
+## Development Setup
+
+### Prerequisites
+
+- Go 1.25 or later
+- Git
+- (Optional) golangci-lint for local linting
+
+### Getting Started
+
+```bash
+# Clone the repository
+git clone https://github.com/steveyegge/beads
+cd beads
+
+# Build the project
+go build -o bd ./cmd/bd
+
+# Run tests
+go test ./...
+
+# Run with race detection
+go test -race ./...
+
+# Build and install locally
+go install ./cmd/bd
+```
+
+## Project Structure
+
+```
+beads/
+├── cmd/bd/              # CLI entry point and commands
+├── internal/
+│   ├── types/           # Core data types (Issue, Dependency, etc.)
+│   └── storage/         # Storage interface and implementations
+│       └── sqlite/      # SQLite backend
+├── .golangci.yml        # Linter configuration
+└── .github/workflows/   # CI/CD pipelines
+```
+
+## Running Tests
+
+```bash
+# Run all tests
+go test ./...
+
+# Run tests with coverage
+go test -v -coverprofile=coverage.out ./...
+go tool cover -html=coverage.out
+
+# Run specific package tests
+go test ./internal/storage/sqlite -v
+
+# Run tests with race detection
+go test -race ./...
+```
+
+## Code Style
+
+We follow standard Go conventions:
+
+- Use `gofmt` to format your code (runs automatically in most editors)
+- Follow the [Effective Go](https://golang.org/doc/effective_go) guidelines
+- Keep functions small and focused
+- Write clear, descriptive variable names
+- Add comments for exported functions and types
+
+### Linting
+
+We use golangci-lint for code quality checks:
+
+```bash
+# Install golangci-lint
+brew install golangci-lint  # macOS
+# or
+go install github.com/golangci/golangci-lint/cmd/golangci-lint@latest
+
+# Run linter
+golangci-lint run ./...
+```
+
+CI will automatically run linting on all pull requests.
+
+## Making Changes
+
+### Workflow
+
+1. Fork the repository
+2. Create a feature branch (`git checkout -b feature/my-feature`)
+3. Make your changes
+4. Add tests for new functionality
+5. Run tests and linter locally
+6. Commit your changes with clear messages
+7. Push to your fork
+8. Open a pull request
+
+### Commit Messages
+
+Write clear, concise commit messages:
+
+```
+Add cycle detection for dependency graphs
+
+- Implement recursive CTE-based cycle detection
+- Add tests for simple and complex cycles
+- Update documentation with examples
+```
+
+### Pull Requests
+
+- Keep PRs focused on a single feature or fix
+- Include tests for new functionality
+- Update documentation as needed
+- Ensure CI passes before requesting review
+- Respond to review feedback promptly
+
+## Testing Guidelines
+
+- Write table-driven tests when testing multiple scenarios
+- Use descriptive test names that explain what is being tested
+- Clean up resources (database files, etc.) in test teardown
+- Use `t.Run()` for subtests to organize related test cases
+
+Example:
+
+```go
+func TestIssueValidation(t *testing.T) {
+    tests := []struct {
+        name    string
+        issue   *types.Issue
+        wantErr bool
+    }{
+        {
+            name:    "valid issue",
+            issue:   &types.Issue{Title: "Test", Status: types.StatusOpen, Priority: 2},
+            wantErr: false,
+        },
+        {
+            name:    "missing title",
+            issue:   &types.Issue{Status: types.StatusOpen, Priority: 2},
+            wantErr: true,
+        },
+    }
+
+    for _, tt := range tests {
+        t.Run(tt.name, func(t *testing.T) {
+            err := tt.issue.Validate()
+            if (err != nil) != tt.wantErr {
+                t.Errorf("Validate() error = %v, wantErr %v", err, tt.wantErr)
+            }
+        })
+    }
+}
+```
+
+## Documentation
+
+- Update README.md for user-facing changes
+- Update relevant .md files in the project root
+- Add inline code comments for complex logic
+- Include examples in documentation
+
+## Feature Requests and Bug Reports
+
+### Reporting Bugs
+
+Include in your bug report:
+- Steps to reproduce
+- Expected behavior
+- Actual behavior
+- Version of bd (`bd version` if implemented)
+- Operating system and Go version
+
+### Feature Requests
+
+When proposing new features:
+- Explain the use case
+- Describe the proposed solution
+- Consider backwards compatibility
+- Discuss alternatives you've considered
+
+## Code Review Process
+
+All contributions go through code review:
+
+1. Automated checks (tests, linting) must pass
+2. At least one maintainer approval required
+3. Address review feedback
+4. Maintainer will merge when ready
+
+## Development Tips
+
+### Testing Locally
+
+```bash
+# Build and test your changes quickly
+go build -o bd ./cmd/bd && ./bd init --prefix test
+
+# Test specific functionality
+./bd create "Test issue" -p 1 -t bug
+./bd dep add test-2 test-1
+./bd ready
+```
+
+### Database Inspection
+
+```bash
+# Inspect the SQLite database directly
+sqlite3 .beads/test.db
+
+# Useful queries
+SELECT * FROM issues;
+SELECT * FROM dependencies;
+SELECT * FROM events WHERE issue_id = 'test-1';
+```
+
+### Debugging
+
+Use Go's built-in debugging tools:
+
+```bash
+# Run with verbose logging
+go run ./cmd/bd -v create "Test"
+
+# Use delve for debugging
+dlv debug ./cmd/bd -- create "Test issue"
+```
+
+## Release Process
+
+(For maintainers)
+
+1. Update version in code
+2. Update CHANGELOG.md
+3. Tag release: `git tag v0.x.0`
+4. Push tag: `git push origin v0.x.0`
+5. GitHub Actions will build and publish
+
+## Questions?
+
+- Check existing [issues](https://github.com/steveyegge/beads/issues)
+- Open a new issue for questions
+- Review [README.md](README.md) and other documentation
