fix(hosting): keep a free-disk floor before taking a copy - #205

Conversation
Every node hosts by default since #199, including busy production boxes, and the only guard was the 5 GiB hosting budget: dev2 runs ~6 c0mpute processes that now all host, on a 1.8 TiB disk with 20 GiB free. replicate() now refuses a copy unless max(10 GiB, 5% of the disk, capped at 50 GiB) stays free.

Since #199 every node (and every single-role worker) hosts by default. The only limit on copies was the 5 GiB hosting budget per process, which ignores how full the disk already is: dev2 (production) runs ~6 c0mpute processes that all host now, on a disk with ~20 GiB free.
replicate()now refuses a new copy unless max(10 GiB, 5% of the disk), capped at 50 GiB remains free after it. A disk the OS cannot report (0/0) falls back to the budget check alone. Healing simply picks another host.Unit test covers the floor math, the dev2 case (20 GiB free of 1.8 TiB: refuse), the exact boundary and the unknown-disk case.
