This function reports whether the caller's disk usage is already at or near the limit that would block a new WordPress installation. The check reserves headroom for the install itself, so it can report 1 before the account has actually exceeded its quota.

Note:

• The onboarding flow calls this up front, before it offers to install WordPress, so it can explain the refusal instead of failing partway through create_website.
• This function takes no parameters and has no failure path of its own, beyond the wp-toolkit feature that every function in this module needs. A caller that holds the feature always gets a successful status.
• create_website repeats the same check and refuses with an error when the quota blocks the install.
