feat: add excludePatterns parameter to violation reporting tools

[AbdulRehaman08]

Add optional excludePatterns parameter to report-violations and report-all-violations tools, enabling users to exclude files/directories from violation scans using glob patterns.

Features:

• Supports single string or array of glob patterns
• Standard glob syntax: *, **, ?
• Custom glob-to-regex converter (no external dependencies)
• Pre-compiled regexes per run for performance on large result sets
• Reuses existing normalizeFilePath for consistent path handling
• Post-processing filter approach (filters after plugin execution)
• Score recalculation — audits with all issues excluded get score: 1
• Cross-platform path normalization
• Fail-fast validation with clear error messages

Changes:

• Add excludePatterns to schema definitions (schema-helpers.ts)
• Update type interfaces across all layers
• Implement pattern matching in coverage-analyzer.ts using normalizeFilePath from formatters.ts
• Pass excludePatterns through base-analyzer.ts via spread ({ ...options, cwd, ... })
• Update both tool handlers to accept and forward parameter

Examples:

• Single: excludePatterns: "node_modules/**"
• Multiple: excludePatterns: ["node_modules/**", "**/dist/**", "**/*.spec.ts"]

Build: Passes successfully without errors
Backward Compatible: Optional parameter, no breaking changes
