Feature: CLI enhancements — dry-run, output formats, watch mode, shell completions

[jongalloway]

Enhance CLI experience with:

• --dry-run flag (preview changes without modifying file)
• --output-format option (JSON, CSV, table for all commands)
• --watch mode (continuous file monitoring)
• shell completion scripts (bash, zsh, PowerShell via System.CommandLine)

Business value: safer operations, scriptability, developer productivity.

Complexity: Medium. Note: depends on CLI interface (#94) shipping first.
