Refuse build steps under a free-space floor and release workspaces, so the build modules stop filling a build node's disk (issue 1839)

mesh-build-go, mesh-build-node and mesh-build-image refuse every fetch, test and build, and say unhealthy, while their work or cache filesystem has less than 20 GiB free (build-agent's floor), so the builder chooses another node instead of filling this one. Each serves build_<x>_release, removing a workspace once its caller's last step answered; a failed fetch removes its own; a workspace never released goes two hours after its last use (ADR 0509) in place of a day, never while a step holds it. Pins mesh-sdk's fix/1839-build-floor (buildstep.Floor, buildstep.Workspaces).

-What is real and what is a stand-in:
-
- **Real:** every page, form, template, the script and the stylesheet, the content security policy, the host
-  check and the form tokens: `internal/web` as the module runs it.
- **Stand-ins, in memory, gone when it stops:** the mail — about 25 invented mails in two accounts, `work` and
-  `personal`, with design 63's mockup people and firms (Sara Claes, Tim Jacobs, Lena Janssens, the Harbor demo,
-  Hostco, Telco) at `.example` addresses; mail reading — invented entries with tasks, promises and read later in
-  every section, handled, undone, reminded and corrected by the same rules as mesh-mail-reader; the setting
-  `modes` (Work is `work`, Personal is `personal`); and sign-in, always signed in as a stand-in operator.
- **Nothing reaches the mesh:** no bus, no database, no Keycloak, no mail server; a send answers an invented
-  id, is waiting once, then says sent, and no mail leaves the machine.
-
-It is not part of the module's build: `module.json` builds `cmd/mesh-mail-web` alone.
