feat: v0.8.2 clickable paths, alert sessions, ops guard and trail

- Terminal link provider: printed paths that are files of the session open
  in Files (at the line); the file list is preloaded so the first hover works.
- Alerts: "In a new session" opens alert-<name> and types the prompt once
  Claude is up.
- devdesk-guard PreToolUse(Bash) hook: permissionDecision "ask" for
  destructive commands (verified to prompt in auto mode); DEVDESK_GUARD and
  guard.local.
- State hook logs Bash commands and derives host tags (ssh targets, CT/VM
  ids); --list carries tags, --peek the last commands; UI shows both.
