Synced from monorepo

Changes:
- Stop hooks for session lifecycle
- Add x.ai/session/state and x.ai/session/import ACP methods
- Deny-and-continue for auto-mode classifier blocks with denial limits
- Drop codebase-upload from dhat soak test
- scheduler_create upsert via task_id; retire one-shot tasks
- Clipboard: copy file fallback + honest toasts for SSH/Apple Terminal
- Polarity-safe syntax colors in minimal mode
- Auto mode classifies unvetted env prefixes instead of hard-prompting
- Add GROK_CLIPBOARD_NO_OSC52 kill switch to force OSC 52 off
