FastPlay v0.4.6

FastPlay 0.4.6 adds a frameless windowed mode that stays out of the way and
remembers how you left it, fixes portrait videos opening inside a landscape
window, and makes the portable Windows build reproducible from the repository.

Highlights

Toggleable frameless windowed mode

• Press Ctrl+Shift+S to switch between framed and frameless windowed modes.
  The existing Ctrl+S screenshot shortcut is unchanged.
• Move a frameless instance by dragging anywhere in the visible client area
  outside the timeline. Ctrl+Drag still pans zoomed video.
• Resize from every edge and corner with DPI-aware hit targets.
• Fullscreen, maximize, restore, timeline interaction, and the normal shutdown
  path continue to work in either mode. No window animations were added.

Remembered across new instances

• FastPlay saves the selected window style in
  %APPDATA%\FastPlay\settings.txt and applies it when a new process starts.
• A new process is created directly in the preferred style, avoiding a framed
  flash before switching to frameless mode.
• Existing settings files containing only volume= remain compatible. Toggling
  back to framed mode updates the same preference immediately.

Portable packaging in the repository

• The PowerShell packager creates a versioned Windows x64 ZIP from the release
  build and keeps its runtime DLL set aligned with the WiX installer manifest.
• The archive includes portable usage guidance and third-party notices. FastPlay
  itself continues to store settings, recent files, resume positions, and logs
  under %APPDATA%\FastPlay.

Portrait videos open without empty side space

• FastPlay now applies 90-degree and 270-degree display-matrix rotation before
  sizing the window for the first frame.
• Phone videos stored as landscape-coded frames with portrait rotation metadata
  now open in a portrait window instead of a landscape window with large black
  side areas. Native portrait and unrotated landscape sizing are unchanged.

Updated Windows icon

• The executable, installer, Start menu, and video file associations now use the
  supplied FastPlay mark, with dedicated icon entries from 16 through 256
  pixels.
• The installer registers an exact standalone copy for both FastPlay's file type
  and Windows' per-user application association, avoiding stale executable-icon
  fallbacks on Explorer video thumbnails.

Performance

The frameless implementation does not change the steady-state playback path.
Local A/B launch measurements found no regression:

• frameless window implementation, 15 samples per revision: open-to-first-frame
  p50 56 ms before and after; p95 74 ms before and 65 ms after
• persisted startup preference, 30 alternating samples: launch-to-window p50
  28.3 ms before and 25.9 ms after; p95 36.4 ms before and 36.0 ms
  after

These measurements describe one development machine and are not universal
latency claims.

Validation

• cargo fmt --check
• cargo clippy --all-targets -- -D warnings
• cargo test --all-targets (267 passing)
• cargo build --release
• cargo wix
• live window-geometry checks for native portrait, 90-degree metadata-rotated
  portrait, and unrotated landscape clips
• portable ZIP structure plus extracted hardware-D3D11 and software-fallback
  playback checks
• MSI administrative extraction and extracted-payload hardware playback check
• installed MSI in-place upgrade from 0.4.5 to 0.4.6
• multi-process framed → frameless → framed persistence validation with isolated
  temporary settings

Upgrade notes

• Existing installs upgrade in place through the MSI major-upgrade path.
• No account, network connection, or settings migration is required.
• Use Ctrl+Shift+S at any time to return new instances to framed mode.
