feat(flags): add env var support for dry, yes, and silent flags

Add environment variable configuration for three CLI flags:
- TASK_DRY: enable dry-run mode without executing tasks
- TASK_ASSUME_YES: automatically answer yes to prompts
- TASK_SILENT: disable command echoing (also supports taskrc config)

The silent flag gets full support with both taskrc configuration
and environment variable, while dry and yes are env-var only.
