enricobuehler ee5e89d7d3 feat: the daily-driver five — 10-bit SDR, system keys in desktop mode, keep-host-audio, mode env for prep, cursor at client DPI ...

Five field requests from one returning user, traced and fixed together
(report: the "Daily-Driver Five" triage).

**10-bit SDR, independent of HDR.** VIDEO_CAP_10BIT and VIDEO_CAP_HDR were
always separate wire bits, but everything above the wire welded them: the
client advertised both from one "HDR" switch, the handshake required an HDR
capture source for any 10-bit depth, SessionPlan derived hdr from bit_depth,
and the encoder stamped BT.2020 PQ on every 10-bit format. Now a client
setting ("10-bit SDR", default off, tier-P) advertises the depth bit alone;
the handshake resolves bit_depth=10 without the HDR gates where the SDR-10
chain exists (Windows IDD-push + direct NVENC + HEVC — everywhere else the
session stays 8-bit, said honestly in the Welcome); the Welcome's colour
label, the virtual display's HDR bring-up and the capturer's want-HDR flag
all follow the new session-hdr verdict instead of the depth. The capture
side grows PixelFormat::Rgb10a2Sdr — the BGRA slot expanded 8→10 by a
trivial full-res pass (HdrRgb10Converter::new_sdr_expand) — which NVENC
ingests as ABGR10 and encodes Main10 under the ordinary BT.709 SDR VUI,
both 4:2:0 and 4:4:4. The win is the ENCODER's precision (compression
stops adding banding to gradients); the desktop stays 8-bit and neither
display's colour state is touched. The client already decodes by the VUI,
so no decode-side change was needed.

**"Capture system shortcuts" now works in Desktop mouse mode.** The setting
was wired end to end and then discarded by one `!desktop` term in the
presenter's grab condition — documented as "a remote desktop is something
you Alt-Tab away from", which made the toggle inert for exactly the
remote-desktop use it matters most for. The keyboard grab now follows the
setting in BOTH mouse models; desktop mode keeps an escape capture mode
never had (the unlocked pointer clicks any other window, focus drops, the
chords come back). Docs updated; the Mac's ⌘-chord behaviour is unchanged.

**Keep host audio playing (Moonlight's "Mute host PC speakers", unchecked,
per session).** New client setting + CLIENT_CAP_KEEP_HOST_AUDIO (0x20,
request-only, no HOST_CAP echo — an older host just re-routes as always).
A session holding the bit gets the host's audio devices left alone for its
lifetime (RAII guard): Windows skips the IPolicyConfig default parking and
loopbacks the operator's own default device; Linux taps the default sink's
monitor instead of claiming the default. Host-global best-effort across
concurrent sessions, as the cap documents. Rows in the GTK, Windows and
console-UI settings (desktop-only until Android advertises the bit).

**Prep commands carry the negotiated mode.** A per-app do/undo step's whole
environment was PF_APP_ID; the width/height/refresh/HDR it needs for a
per-mode frame cap were resolved 80 lines above and written only to the
unix-only marker file. Both serving planes now pass PF_STREAM_WIDTH /
_HEIGHT / _REFRESH / _HDR (the marker file's vocabulary, via one shared
hooks::prep_mode_env) — so an RTSS cap is one step instead of one
hard-coded entry per device, on Windows hosts too.

**The forwarded cursor matches the client's DPI.** The desktop-mode pointer
was resampled by the video fit factor alone, and SDL shows a custom cursor
surface at ~1:1 physical pixels on every backend — so on a 200% client our
pointer was half the size of every native one (and X11 the same; Wayland
escapes via buffer scale). The resample factor now folds in
SDL_GetWindowDisplayScale, the same model the Apple client gets for free
from point-sized NSCursors.

Verified: workspace clippy --locked -D warnings + targeted tests (hooks,
profiles, caps, console-ui rows, capture-policy) green on Linux
(pf-gtkflow); pf-capture/pf-frame windows-msvc green via xcheck; rustfmt
clean. NOT verified: the Windows-only halves of pf-encode/punktfunk-host
(no reachable Windows toolchain — .133 down; windows-host.yml is
dispatch-only, see the preceding commit), and everything on-glass: the
SDR-10 stream end to end, the desktop-mode grab, keep-host-audio wiring,
prep env on a live launch, and the cursor size at 200%.

fix(host): the Linux data-plane renice was a silent no-op everywhere — fall back to RealtimeKit, and boost the audio threads at all
