LeaseProvider

• acquire grants the key when it is free or expired (a new, larger token), or extends it when owner already holds it (same token); else returns null.
• renew extends the lease only when owner still holds it with token.
• release frees the key only when owner holds it with token (else no-op). Tokens never go backwards for a key, even across release and expiry.
