fix(cli): subnet status membership is trust-derived — rowless members render

Field report (re-join 2026-06-06): freshly re-joined BIGNET, 'subnet
status' (bare and --nodes) showed only gravity — the joining machine
itself missing from its own subnet view. Both views derived node
membership purely from registry rows, so a member with zero advertised
endpoints (fresh box, empty owlery) was invisible — and the 4.10
eviction made it worse: an offline peer's rows decay, vanishing the
node instead of rendering it offline.

Membership now seeds from the durable pairing truth — self + the trust
store's pinned peers — with registry-row nodes unioned in as

fix(store,daemon,runtime): CREATE_NO_WINDOW on console children of the daemon

Field report (2026-06-06): two blank windows flashed on the desktop
every 60 seconds. A process-spawn watcher caught the culprit pair —
the sync pump's git calls (for-each-ref + rev-parse against
context\.seed.git), spawned by the console-less DETACHED daemon. A
console-subsystem child of a console-less parent allocates a fresh
conhost with a VISIBLE window; piped/null stdio does not prevent it.

Confirmed hypothesis: spt-store::gitrun::run_git set no
creation_flags, so every BranchStore/ContextStore git call flashed a
window when invoked from the daemon. Same class, fixed in the same
sweep: shellhost::kill_shell_pid (taskkill on teardown) and
spt-runtime::run_bounded_command (manifest hook commands). shellwake
already carried the flag — the lesson existed in-repo but was not yet
an invariant.

Recorded as KNOWN-HAZARDS 5.8 / REQ-HAZARD-CHILD-CONSOLE-FLASH.
Test-seam caveat documented: window-absence is unobservable from a
consoled test runner (the child inherits the runner's console), so
unit coverage asserts the flagged spawn works (the error-87 flag-combo
regression class, cf. c7e7d9e); window-absence verified live by
watcher before/after.

Touched files include pre-existing rustfmt rewrap churn that was
already in the working tree.
