feat: implement URL replacements for enterprise networks
Implements URL replacements feature as requested in issue #40, enabling mvx to work in enterprise environments with internal mirrors and proxies. Features: - Global URL replacement configuration in ~/.mvx/config.json5 - Support for simple string replacements (github.com -> nexus.internal) - Support for regex replacements with capture groups - CLI commands for managing URL replacements - Automatic integration with all tool downloads - First-match-wins processing for predictable behavior - Comprehensive validation for regex patterns New CLI commands: - mvx config show - Display current global configuration - mvx config set-url-replacement <pattern> <replacement> - mvx config remove-url-replacement <pattern> - mvx config clear-url-replacements - mvx config edit - Open config file in editor Files added: - pkg/config/global.go - Global configuration management - pkg/tools/url_replacements.go - URL replacement logic - cmd/config.go - CLI commands for configuration - website/content/url-replacements.md - Documentation - pkg/tools/url_replacements_test.go - URL replacement tests - pkg/config/global_test.go - Global configuration tests Files modified: - pkg/tools/download.go - Integrated URL replacements - cmd/root.go - Added config command - README.md - Added feature documentation The implementation uses global-only configuration for security and simplicity, avoiding the complexity of project-level overrides. Closes #40
