- Explicit `connections:` entries now charge the slot ledger like the
generated ones (dev let them evade the controller budget); pinned by a
test
- set_enabled(true) clears the connect backoff - a re-enable is an
explicit try-again
- The neutral engine's source filter uses the shared
frameworks_for_platforms helper; ledger tests use the conftest fixture
- abort_service_stream() on the wrapper (which owns the latch discipline)
replaces five identical field-poke sequences in the streamer
- The pre-start reuses check_and_log_error_ like the serialized path
- discover_services() sets the requested flag where it sticks instead of
set-then-rollback; deliver_pending_search_() returns void (no caller
reads it); loop()'s IDLE arm folds into the settle arm
- SEARCH_CMPL during a teardown skips the param/count work whose result
is never delivered
- frameworks_for_platforms() in config_helpers derives framework sets
from platform lists; the hub.cpp filter entry is now a named map pinned
by a test against the proxy's platform list
