AutoContext: Context Operator

Not just a health check — a full operator over everything that shapes context. Three layers by action sensitivity:

Layer	Examples	Behavior
Auto-execute	write project memory, update `MEMORY.md` index	Do it, report path
Confirm-first	edit global agent instructions, edit project `CLAUDE.md`, overwrite/delete existing memory	Show diff, wait for "yes"
Suggest-only	`/fork`, `/compact`, `/btw`, new session	Print the exact command to paste

The harness owns /fork and /compact; this skill cannot invoke them. But it can do everything else and will.

Auto Mode (via Plugin Hook)

When the lovstudio plugin is enabled, a UserPromptSubmit hook monitors transcript size. Above threshold (40+ entries or 150KB+), it injects a lightweight <auto-context> reminder.
