feat(tsconfig): implement solution-style tsconfig resolution

[shulaoda]

closes #790

Implement solution-style tsconfig resolution similar to tsconfck' resolveSolutionTSConfig. This automatically selects the correct tsconfig for a file in monorepo/solution-style projects with project references.

Changes:

• Add TsConfig::resolve_for_file method to resolve the appropriate tsconfig based on file inclusion patterns
• Add TsConfig::is_file_included to check if files match tsconfig's include/exclude/files patterns
• Add TsConfig::is_glob_match for glob pattern matching with support for TypeScript's pattern normalization
• Integrate solution-style resolution in TsconfigDiscovery::Auto mode
• Add fast-glob dependency for efficient pattern matching
• Add comprehensive test suite with 6 tests covering basic resolution,
  exclude patterns, allowJs, extensions, and edge cases
• Add test fixtures for monorepo scenarios with multiple packages

The implementation respects TypeScript's file inclusion rules including:

• files array (highest priority)
• include patterns with implicit **/* globstar
• exclude patterns
• allowJs configuration for JavaScript files
• All TypeScript extensions (ts, tsx, mts, cts, js, jsx, mjs, cjs)

I’ll add more tests for the is_file_included and is_glob_match methods in the next PRs.

Pull Request Overview

This PR implements solution-style TypeScript configuration resolution for monorepo projects with project references. The implementation follows similar logic to tsconfck's resolveSolutionTSConfig, ensuring that files are resolved against the correct tsconfig in a multi-project setup.

Key changes:

• Added resolve_for_file method to determine the correct tsconfig for a file in a solution-style project
• Implemented file inclusion/exclusion logic with is_file_included and is_glob_match methods
• Integrated the new resolution logic into the main resolver workflow
