fix socket FD leak during reconnection in IORing connection backends

Release existing IORing socket (via deinit) before creating a new one
during reconnection retries. For domain socket connections, also unlink
the previous bound address.

refactor OCABrowser and SwiftOCAUI for connection broker, block navig…

…ation, and view fixes

OCABrowser:
- Use OcaConnectionBroker for device discovery on both macOS and iOS
- Show device list in NavigationSplitView sidebar with protocol type
- Remove macOS-only BonjourBrowser and File menu device selection

SwiftOCAUI block navigation:
- Rewrite OcaBlockNavigationSplitView with drill-down sidebar navigation
- Leaf-only blocks show all members in a grid (max 4 columns) in detail
- Blocks with sub-blocks drill down via selection in sidebar

View dispatch fixes:
- Move OcaViewRepresentable conformances to DetailView.swift to ensure
  protocol conformance metadata is linked (static library stripping fix)
- OcaDetailView uses already-resolved objects directly instead of
  re-resolving, preserving dynamic type information
- Remove stale Combine imports

Actuator/sensor view fixes:
- Fix BoundedProperty._setValue to accept both OcaBoundedPropertyValue<V>
  and raw V types, fixing gain/slider commands not reaching the device
- Remove Combine-based debounce from VariableSliderView for immediate
  slider tracking during drag
- Remove .id(value.value) from LogSliderView that was destroying the
  slider on every value change
- Add minHeight to LogSliderView for proper vertical fader sizing

Level meter:
- Rewrite OcaLevelSensorView as vertical bar graph with PPM ballistics
- 10ms EMA attack, 14 dB/s linear decay (matching inferno_ui)
- Color-coded segments: green/yellow/orange/red
- dBFS scale markings

don't infer addImageData() asynchronous nature automatically

instead, make it a function parameter (with a default value of true). not all
devices can handle out-of-order updates.

make sendMessages, rather than sendMessage, mandatory to implement

cache device property method IDs

Revert "make device-side locking functions public"

This reverts commit 07cb5d2.

dion't use @_alwaysEmitIntoClient on any platform, crashes with 6.1-dev

add OcaTemperatureSensor

move connection objectWillChance() into _updateConnectionState()

switch back to main branch of FlyingFox
