The Apple client now consumes the connector's clock offset. PunktfunkConnection
reads punktfunk_connection_clock_offset_ns into clockOffsetNs at connect; a new
LatencyMeter (PunktfunkKit, NSLock + percentiles, mirrors FrameMeter) records each
AU's capture->client-receipt latency = now(CLOCK_REALTIME) + offset - pts_ns, and
SessionModel drains p50/p95 into the macOS HUD ("capture->client N/N ms p50/p95",
"(same-host)" when the host didn't answer the skew handshake). Wired at the
existing onFrame hook in ContentView — additive, no change to the decode/present
path. Unit test for the meter (percentiles, skew flag, absurd-value guard).
This is the first cross-machine latency the real Apple client reports. SCOPE:
stage-1 AVSampleBufferDisplayLayer decodes+presents compressed samples internally
with no per-frame callback, so this excludes decode+present; true decode->present
needs the stage-2 presenter (VTDecompressionSession + CAMetalLayer). Rebuild
PunktfunkCore.xcframework (for the new C getter) before swift build/test on a Mac.

Factor the client-side skew handshake into a shared core helper (quic::clock_sync
-> ClockSkew) so both the reference client and the embeddable connector use one
implementation. NativeClient now runs the handshake at connect (right after Start,
before the control task takes the stream) and stores the host-client offset; it's
read over the C ABI via punktfunk_connection_clock_offset_ns (i64 ns, host minus
client; 0 = no correction / old host).
This is the substrate the Apple client needs for the decode->present (glass-to-
glass) term: stamp present time, add the offset to express it in the host's
capture clock, subtract the AU pts_ns. client-rs drops its local clock_sync copy
and uses the shared helper (behavior unchanged; validated locally).
Regenerates include/punktfunk_core.h. Roadmap section 12 + status updated.

Per the new docs workflow (docs-site = KB layer; repo docs/ keeps design notes):
- Add a canonical Status & Progress tracker (status.md): milestones, per-box live
state, and a dated progress log — the go-forward place to track progress.
- Add setup guides: GNOME/Mutter host (gnome-box — Secure Boot MOK enroll, the
libnvidia-gl EGL fix, autologin, screen-lock disable, appliance unit), headless
KDE box, and Bazzite host (ujust input group, gamescope session, gotchas).
- Roadmap is now canonical in docs-site (synced the skew-handshake section 12
update); removed the repo docs/roadmap.md copy and repointed README to docs-site.
- Nav (meta.json) + landing cards updated; site builds (bun run build).
