ask: default to list, add ask all for complete task visibility

- ask (no args) now behaves like ask list (active tasks sorted by priority/urgency)
- ask help: explicit help subcommand
- ask all: shows ALL tasks including completed/deleted (uses status:any)
- handleAll added in command_list.go, mirrors handleList with status:any
- Updated tests: help tests use explicit 'ask help', all subcommand added to reachability test
- Updated help text to document ask all
