Layout persistence: re-enable io.IniFilename (was nullptr "for the spike"),
anchored to a coop_layout.ini next to the exe so window positions/sizes survive
restarts even when Steam launches us under the donor appid (CWD is unreliable).
Path is UTF-8 for ImGui's file IO. When a saved layout is restored at startup,
suppress the computed-default force so it does not clobber the user's positions;
Reset layout (and a fresh install with no .ini) still applies the default.
Log spam: the worker thread re-attaches every audio ring every tick (idempotent),
and set_audio_ring logged unconditionally, flooding the log. Only log when the
ring pointer actually changes.

Panels used to Begin at cascade positions, so they overlapped and clipped. A new
apply_panel_layout() in app_chrome positions/sizes each panel from the main
viewport work area (ImGuiCond_FirstUseEver, still movable): Injection left column
full height (room for hook diagnostics), Controllers/Video/Audio stacked in the
center column, Log right edge full height (max room for the log stream). Added a
"View -> Reset layout" menu item (request_layout_reset / apply_layout_end_frame
re-apply the defaults once via ImGuiCond_Always). Each panel now calls
apply_panel_layout(Panel::X) instead of its own ad-hoc SetNextWindowPos/Size.
Verified live: captured the host overlay -- Injection (left, full height),
Controllers/Video/Audio (center stack), Log (right, full height), no overlap among
the panels. x64 build + ctest green.

Add a shared log ring (common/coop/log_ring.hpp): a lossy multi-producer /
single-consumer ring named coop_log_<pid>. The hook logs from several threads,
so producers claim a slot with fetch_add and publish each record with a
release store of its sequence; the consumer reads in order and tolerates
losing the oldest lines if it falls a whole ring behind.
The DLL's logf() now formats once and pushes every line to the ring (the file
trace stays as an opt-in mirror); the worker attaches the ring right after IPC
connect so bring-up is captured. The host (IpcServer) creates the ring at
injection time and exposes drain_logs(); a new LogPanel pulls new lines each
frame into a bounded rolling buffer and renders them with auto-scroll, a
filter, and clear. Added to the View menu (and UiState.show_log).
Verified against Phantom Brave via coop_audio_probe, which now also creates the
ring and drains it: the full hook bring-up trace streamed over IPC. All four
tests pass.

The mirror renders into the host window, so the host's render frame timing is
the mirror's performance. FrameStats now retains a ~2 s ring of frame-time
samples; the Video mirror panel plots them as a frametime graph (0-33 ms
scale) and an FPS graph (0-144 scale), each with an avg overlay, and prints
avg/min/max for both frametime and FPS underneath.

Add a top menu bar (host/src/ui/app_chrome) as the overlay shell:
- View menu toggles each panel (Controllers / Injection / Video / Audio)
and a global "Debug details" switch (consumed by panels in a follow-up).
- A right-aligned performance readout: stable 1 s FPS plus the frame-time
spread (avg, min-max) so stutter is visible; it turns amber on a >25 ms
spike. FrameStats keeps the rolling window.
Consolidates the FPS that was duplicated in the controllers and video
panels into this one readout.
First structural step of the "generalize the UI" roadmap task; content
rework (debug-vs-general split, renaming the spike-era readouts) follows.
