Generating Store Layer methods based on Yaml files

[coolwednesday]

Add Store Layer Generator to gofr-cli

Pull Request: Enhanced Store Generator & Documentation Overhaul

Overview

• Closes Create Store layer for GoFr Framework Users #63

Key deliverables:

1. generator.go
2. templates.go – all code-gen templates extracted into constants with trimmed whitespace, improved spacing, and descriptive comments.
3. example.yaml – end-to-end sample that mixes external and generated models across four stores (user, product, order, category) showcasing every query & return type.
4. README.md – expanded guide covering:
   • robust appending logic and duplicate prevention in stores/all.go
   • CLI commands (init / generate) and multi-store workflow
   • step-by-step main.go integration, registry usage, DI pattern, env overrides
   • advanced YAML examples, troubleshooting tips, and linter guarantees.
5. Tested Improvements
   • correct handling of import sections whether absent or present
   • explicit file-close calls inside loops
   • fallback regeneration when registry parsing fails

---

How to Test

1. gofr store init -name=user then gofr store init -name=product – check stores/all.go appends without dupes.
2. gofr store generate -config=example.yaml – generates four stores and a clean registry; go vet ./... and go test succeed.

---

Backward Compatibility

• Single-store YAML format is supported.
• Existing stores/all.go files are preserved—new stores append safely.
• No breaking API changes to generated interfaces or method signatures.

---

Next Steps

• Optional: add integration tests that compile generated code in CI.
• Consider packaging CLI as a standalone binary for non-GoFr projects.

Pull Request Overview

This PR adds a comprehensive store layer generator to gofr-cli that generates GoFr-compatible store interfaces and implementations from YAML configuration files. The generator supports multi-store architecture with external model referencing and smart generation features.

• Adds YAML-driven store layer code generation with CRUD operations support
• Implements multi-store architecture allowing multiple isolated stores in a single configuration
• Introduces external model referencing to use existing model files instead of generating new ones
