v0.95.0: SMART coverage — union-path drives + LVM/dm root + device model

Browse Source 
Implements SPIKE-smart-coverage-2026-07-25 fixes B+A (additive; MinAgent unchanged).
Fix B: storage.SmartReader.SMARTForBacking wired into the /disks union path (localapi
Smart seam) so registry/USB drives get a real SMART read (watchdog Known stays
enrich-free). Fix A: smartDeviceFor resolves dm/LVM to the whole disk via
/sys/block/<dm>/slaves (recursive; skips >1-disk); the builtin local dir on the LVM
root gets a SMART-only device from its containing filesystem (never touches
backing/durable_id). SmartSummary.ModelName captured from smartctl. Fix C (-d sat)
stays rejected. Tests + red-proofs (dm multi-disk skip, enrich smartHint, union
routing); Known-path-never-SMARTs asserted.

- Two lsblk `-J` parsers with near-identical structs: `parseLsblkDevice`/`lsblkDevice` (internal/storage/hostops.go) vs `parseLsblkNodes`/`lsblkDev` (internal/storage/claim.go).
- Two smartctl `-a -j` paths: `SudoHostOps.SMART` (internal/storage/hostops.go, parsed `hub.SmartSummary`) vs `Privileged.SMART` (internal/proxmox/privileged.go, raw map).
- **SMART device resolution (v0.95.0):** `smartDeviceFor` (internal/storage/observe.go) resolves partition→disk AND dm/LVM→disk (`dmWholeDisk` in internal/storage/smartdev.go, via `/sys/block/<dm>/slaves`, `sysBlockRoot` test seam). `storage.SmartReader.SMARTForBacking` is the shared read the localapi `/disks` union path uses (Fix B) — do NOT re-implement smartctl parsing. The builtin-`local` SMART device comes from `containingMountDevice` (SMART-only; never feeds backing/durable_id).
- Atomic tmp+rename JSON store implemented 3×: `IntentStore.saveLocked` (internal/storage/intent.go), `FormatJobStore.save` (internal/localapi/formatjob.go), `GuestBindStore.saveLocked` (internal/localapi/guestbindstore.go) — comments say "mirrors", no shared helper.
- `run(ctx, name, args...) error` stderr-wrapping helper duplicated 4×: `SudoHostOps.run`, `Privileged.run`, `BackHalf.run` (internal/provision/backhalf.go), `GuestBinder.run` (internal/localapi/guestbind.go).
- Several independent /proc mount-table readers: `SudoHostOps.mountedSet` (internal/storage/hostops.go), `ProcHostReader.Mounts` (internal/storage/hostread.go), `isHostMountpoint` + `countHostMounts` (internal/localapi/intermediary.go).
