Add code formatting and import organization

[denisvmedia]

Overview

This PR adds code formatting improvements and import organization to enhance code consistency and readability across the project.

Changes Made

✅ golangci-lint Configuration

• Added gci and gofmt formatters to .golangci.yml
• Configured gci (Go import organizer) with proper import sections:
  1. Standard library imports first
  2. Default (third-party) imports second
  3. Project-specific imports last (github.com/stokaro/dev-postgres-mcp)
• Added exclusions for generated code and third-party directories

✅ Code Formatting Improvements

• Logging functions: Removed extra blank lines and improved spacing consistency
• Import organization: Cleaned up import blocks in Docker client files
• Alignment: Fixed indentation and spacing issues
• Consistency: Applied uniform formatting across all modified files

Files Modified

Configuration

• .golangci.yml - Added formatters and import organization rules

Code Cleanup

• internal/docker/client.go - Removed extra blank lines in imports
• internal/docker/health.go - Import organization
• internal/docker/postgres.go - Import organization
• internal/mcp/logging.go - Spacing and alignment improvements
• internal/postgres/manager.go - Minor formatting fixes
• pkg/types/instance.go - Import organization
• test/unit/postgres_test.go - Formatting consistency

Benefits

1. Improved Readability: Consistent formatting makes code easier to read
2. Better Organization: Logical import grouping follows Go best practices
3. Automated Enforcement: Formatters ensure consistency in future changes
4. Reduced Diff Noise: Consistent formatting reduces unnecessary diffs
5. Professional Standards: Follows industry-standard Go formatting conventions

Import Organization Example

Before:

import (
    "context"
    "github.com/docker/docker/api/types"
    "fmt"
    "github.com/stokaro/dev-postgres-mcp/pkg/types"
)

After:

import (
    "context"
    "fmt"
    
    "github.com/docker/docker/api/types"
    
    "github.com/stokaro/dev-postgres-mcp/pkg/types"
)

Testing

• ✅ No functional changes: All modifications are formatting/style only
• ✅ Linting passes: Code meets all formatting standards
• ✅ Build successful: No compilation issues introduced
• ✅ Import organization: Follows Go community best practices

Future Benefits

With these formatters enabled:

• Automatic formatting: golangci-lint run --fix will maintain consistency
• CI enforcement: Formatting issues will be caught in CI/CD pipeline
• Developer experience: Consistent code style across all contributors
• Reduced review time: Less time spent on style discussions

Ready to Merge

• ✅ No functional changes
• ✅ Improves code quality and consistency
• ✅ Follows Go community standards
• ✅ Enables automated formatting enforcement
• ✅ Well-documented configuration
