refactor: remove deprecated individual commands for 1.0.0 release

Browse Source 
Remove all deprecated individual command implementations (complexity, deadcode,
clone, cbo, deps) in preparation for the 1.0.0 stable release. All functionality
is preserved through the unified `pyscn analyze --select <analysis>` command.

Breaking Changes:
- Removed `pyscn complexity` command
- Removed `pyscn deadcode` command
- Removed `pyscn clone` command
- Removed `pyscn cbo` command
- Removed `pyscn deps` command

Migration:
- Use `pyscn analyze --select complexity .` instead of `pyscn complexity .`
- Use `pyscn analyze --select deadcode .` instead of `pyscn deadcode .`
- Use `pyscn analyze --select clones .` instead of `pyscn clone .`
- Use `pyscn analyze --select cbo .` instead of `pyscn cbo .`
- Use `pyscn analyze --select deps .` instead of `pyscn deps .`

Implementation Details:
- Deleted deprecated command files: complexity_clean.go, dead_code.go, clone.go,
  cbo.go, deps.go, clone_config_wrapper.go
- Refactored check.go to use use cases directly instead of deleted command wrappers
- Removed command registrations from main.go
- Deleted associated E2E tests: complexity_e2e_test.go, dead_code_e2e_test.go,
  clone_e2e_test.go
- Removed unused helper function from e2e/helpers.go
- Added .golangci.yml to suppress SA5011 false positives in test files
- Updated CHANGELOG.md with 1.0.0 breaking changes section

Rationale:
This breaking change is made during the beta period (v0.x.x) to:
- Eliminate redundant command interfaces and reduce maintenance burden
- Provide a single, consistent way to run analyses
- Simplify documentation and reduce user confusion
- Clean up the codebase before the stable 1.0.0 release

All tests pass, build succeeds, and lint checks pass.

## [1.0.0] - TBD
### Breaking Changes
- **Removed deprecated individual commands**: Removed `complexity`, `deadcode`, `clone`, `cbo`, and `deps` commands
- **Migration**: Use `pyscn analyze --select <analysis>` instead
- Example: `pyscn complexity .` → `pyscn analyze --select complexity .`
- Example: `pyscn deadcode --min-severity critical .` → `pyscn analyze --select deadcode --min-severity critical .`
- This change simplifies the CLI interface and improves consistency
- All functionality is preserved through the unified `analyze` command

Short: "Analyze CBO (Coupling Between Objects) metrics",
Long: `Analyze CBO (Coupling Between Objects) metrics for Python classes.
CBO measures the number of classes to which a class is coupled. High coupling
indicates that a class depends on many other classes, making it harder to
maintain, test, and reuse.
Examples:
pyscn cbo src/ # Analyze all Python files in src/
pyscn cbo --min-cbo 5 src/ # Show only classes with CBO >= 5
pyscn cbo --sort coupling src/ # Sort by CBO count (default)
pyscn cbo --json src/ # Output as JSON
pyscn cbo --html src/ # Generate HTML report
pyscn cbo --show-zeros src/ # Include classes with CBO = 0
pyscn cbo --include-builtins src/ # Include built-in type dependencies
Sort options:
coupling - Sort by CBO count (default)
name - Sort alphabetically by class name
risk - Sort by risk level (high to low)
location - Sort by file path and line number
Risk levels are determined by thresholds:
Low: CBO <= 5 (default low threshold)

Long: `Detect dead code in Python files using Control Flow Graph (CFG) analysis.
Dead code refers to parts of a program that are executed but whose result is never used,
or that can never be executed. This tool identifies various types of dead code:
Severity levels:
• Critical: Code that is definitely unreachable (after return, break, etc.)
• Warning: Code that is likely unreachable (unreachable branches)
• Info: Potential optimization opportunities
Detection types:
• Code after return statements
• Code after break/continue statements
• Code after raise statements
• Unreachable conditional branches
• Code after infinite loops
Examples:
pyscn deadcode myfile.py
pyscn deadcode src/
pyscn deadcode --json --min-severity critical src/
pyscn deadcode --show-context --context-lines 5 myfile.py`,

This command performs comprehensive dependency analysis including:
• Module dependency graph construction
• Circular dependency detection using Tarjan's algorithm
• Robert Martin's coupling metrics (Ca, Ce, I, A, D)
• Dependency chain analysis
• Architecture quality assessment
• Optional architecture validation against defined layer rules
Architecture Validation:
Always validates dependencies against architecture rules. If rules are defined in
pyproject.toml ([tool.pyscn.architecture]) or .pyscn.toml, they will be used.
Otherwise, automatically identifies common architecture patterns.
Examples:
pyscn deps src/ # Analyze and validate dependencies
pyscn deps --html src/ # Generate interactive HTML report with validation
pyscn deps --strict src/ # Enable strict validation mode
Output formats:
--html - Interactive HTML report with visualizations (recommended)
--json - JSON output for programmatic processing
--csv - CSV output for spreadsheet analysis
--yaml - YAML output
--dot - DOT graph for external visualization tools`,
