chore: update CI workflows and SonarCloud configuration for improved analysis and coverage reporting

- Unified CI workflow with fail-fast behavior, streamlining stages for formatting, linting, testing, and SonarCloud analysis.
- Enhanced SonarCloud configuration to exclude test files and improve security hotspot analysis.
- Removed outdated coverage and lint workflows, consolidating functionality into the main CI pipeline.
- Updated README to reflect changes in CI structure and added details on workflow stages and requirements.

 ## Workflows
 
-### 🔄 CI (`ci.yml`)
+### 🔄 CI (`ci.yml`) - Main Pipeline
-Main continuous integration workflow that runs on every push and pull request.
+**Unified continuous integration workflow with fail-fast behavior.**
 
-**Jobs:**
+The CI pipeline runs sequentially - if any stage fails, subsequent stages are skipped:
-- **validate** - Quick validation (formatting, vet, lint)
+
-- **test** - Run tests with coverage on Go 1.23
+```
-- **test-matrix** - Test on multiple Go versions (1.21, 1.22, 1.23) and platforms (Linux, macOS, Windows)
+fmt → lint → test → sonarcloud
-- **build** - Build verification for all packages and examples
+                  ↘ build
-- **sonarcloud** - Code quality analysis (runs on master/main only)
+```
+
+**Stages:**
+
+| Stage | Description | Depends On |
+|-------|-------------|------------|
+| **fmt** | Format check using `gofmt -s` | - |
+| **lint** | Static analysis with `go vet` and `golangci-lint` | fmt |
+| **test** | Unit tests with race detector + coverage | lint |
+| **sonarcloud** | Code quality & security analysis | test |
+| **build** | Build verification for all packages | test |
+| **ci-success** | Final status check | all |
+
+**Features:**
+- ✅ Fail-fast: stops immediately if any check fails
+- ✅ Codecov integration for coverage reporting
+- ✅ SonarCloud integration for code quality
+- ✅ Go module caching for faster builds
+- ✅ Concurrency control (cancels in-progress runs)

+## SonarCloud Configuration
 
+Security Hotspot analysis excludes:
+- Test files (`**/*_test.go`)
+- CI configuration (`**/.github/**`)
+- Test utilities (`**/testing/**`, `**/testdata/**`)
+- Example code (`**/examples/**`)
+- CLI tools (`**/cmd/**`)
+
+This ensures security analysis focuses on production library code.
