Verifies the selected recording MIME type can also be decoded by the
in-app <video> element via canPlayType(), so that codecs like av1 —
which MediaRecorder.isTypeSupported() reports as supported for encoding
but are not decodable on fresh Windows installs without the AV1 Video
Extension — are not chosen.
Also passes undefined (not an unsupported fallback string) into
new MediaRecorder() when no preferred type is supported, letting the
browser pick a default instead of throwing NotSupportedError.
Replaces the previous 'as ProcessedDesktopSource' cast with a properly
typed LINUX_PORTAL_SOURCE constant.

- electron/main.ts: treat missing sourceId on linux as portal sentinel
so the request handler never calls getSources() (which itself opens
an extra portal dialog) on fresh sessions.
- useScreenRecorder.ts: persist the synthesized portal sentinel via
selectSource() so main has the source set before getDisplayMedia.
Extract acquireLinuxPortalStream() helper to dedupe the three
duplicated getDisplayMedia constraint blocks.
- LaunchWindow.tsx: hide the screen-source selector button (and its
separator) on Linux so users cannot trigger an extra portal dialog
via the dropdown.
Previously on Linux/Wayland, starting a fullscreen recording required three
separate picker interactions: an in-app source dropdown plus two xdg-desktop-portal
dialogs. The duplicate portal dialogs were caused by:
1. resolveBrowserCaptureSource() calling desktopCapturer.getSources() in the
renderer, which itself triggers the portal on Wayland.
2. setDisplayMediaRequestHandler() in main also calling getSources(), which
triggers another portal.
3. Returning a pre-enumerated source id to Chromium, which on Wayland is stale
and forces Chromium to re-prompt via the portal during MediaStream creation.
Additionally, the editor window failed to appear after recording on some
Wayland sessions because 'ready-to-show' did not fire reliably.
Changes:
- LaunchWindow: skip the in-app source dropdown on Linux and start recording
directly; the OS portal becomes the source picker.
- useScreenRecorder: introduce a 'screen:linux-portal' sentinel source. When
set, route capture through navigator.mediaDevices.getDisplayMedia() so the
portal handles selection in a single dialog. Skip resolveBrowserCaptureSource
for the sentinel to avoid an extra getSources() call.
- electron/main: in setDisplayMediaRequestHandler, when the sentinel is set,
skip desktopCapturer.getSources() entirely and return a synthetic source so
Chromium opens the portal exactly once for the actual capture.
- electron/windows: in createEditorWindow, also call win.show() from
did-finish-load as a fallback for Linux/Wayland where ready-to-show may
not fire.
- Change ?? 99 fallback to ?? 100 in finalizing progress label
- Add editor.export.processingAudioEdits i18n key to all 5 locales
- Tighten sourceTimeToOutputTime return type to number (was number|null)
- Remove now-unused totalOutputDurationMs param from scheduleRegionForChunk
- Remove ?? fallbacks at call sites (function always returns a number)
- Add Linux GPU config: use EGL (better Wayland compat), disable VAAPI
video decoder/encoder (many distros ship broken drivers causing
'vaInitialize failed' and preventing renderer from loading)
- Add ready-to-show fallback for HUD window: if did-finish-load never
fires (GPU failure), show the window after 500ms via ready-to-show
