v1.3.0 — Presets, stock recovery and H.264 bitrate controls

This release adds a redesigned interface, complete tuning presets and stock recovery, and extends the experimental H.264 bitrate controls beyond the previous 200 Mbps limit.

• One navigation sidebar with Overview, Stream settings, Diagnostics, Connection, Advanced, Patches & Recovery, Additional settings and Back to stock.
• Save one complete setup per preset, load it for review, then apply it. Stock recovery saves previous tuning and restores verified original components and Valve defaults.
• Fix Start/Stop monitoring buttons flickering during live polling, improve display scaling, and wait for SteamVR settings after codec rollback.
• H.264 now accepts 25–500 Mbps requests throughout the UI, presets, companion and native adapter. AV1 retains 25–200 Mbps. Older companions are detected before sending unsupported high-rate requests.
• The portable bundle includes the guarded AV1/H.264 patching runtime, Python runtime, decoder module and corresponding decoder source. Starting an experimental session still requires the supported Frame kernel/client, Developer Mode, trusted SSH pairing and administrator authentication.

H.264 was tested over the dedicated dongle at 90 Hz with the same moving pattern:

Target	Actual video	Encoded fps	Presentation timeouts
200 Mbps	148.5 Mbps	89.88	0
225 Mbps	166.0 Mbps	89.73	0
250 Mbps	184.6 Mbps	89.59	3
300 Mbps	211.4 Mbps	85.54	51
500 Mbps	56.5 Mbps	14.95	780

225 Mbps was the highest clean short trial (about 41 seconds). Higher targets can severely stall the tested stream; the new control range does not guarantee sustained throughput. A longer confirmation was not run. H.264 still uses a smaller packed image than AV1.

Validation: 47 core tests and 6 companion contract tests passed, alongside native H.264 GPU/ABI checks. Clean-package H.264 and AV1 startup, decoded pattern output and stock rollback were verified on the supported device.
