feat: gif support for profile picture

[TakuyaYagam1]

Summary

• Add animated GIF support for profile pictures (~/.face)
• New ProfileImage component that detects image format via magic bytes (QImageReader) and switches between AnimatedImage (GIF) and CachingImage (static)
• GIF added to file picker filter so users can select .gif files directly

Changes

• CUtils::imageFormat() — new C++ method for format detection without file extension
• components/images/ProfileImage.qml — Loader-based component switching between animated/static rendering
• Updated User.qml (dashboard) and Center.qml (lock screen) to use ProfileImage
• Added gif to valid image types in Images.qml

Pull request overview

Adds animated GIF support for profile pictures (~/.face) by introducing a format-detecting ProfileImage component that switches between animated and static rendering.

Changes:

• Add gif to supported image types/extensions for the file picker.
• Introduce CUtils::imageFormat() (QImageReader-based) for extension-independent format detection.
• Replace CachingImage usage with ProfileImage in dashboard and lock screen profile-picture views.

CI failures are pre-existing and unrelated to this PR:

• No PanelWindow backend loaded - Wayland backend unavailable in CI
• Member "status" not found on type "QObject" - qmllint limitation with Loader.item type resolution
• Unused import qs.utils in Center.qml - false positive, Paths.home is used from it

Quick update: I rebased the PR on top of the latest upstream changes after the new image cache provider merge.

I tested an additional follow-up that moved image format detection into Caelestia.Images.IUtils and disabled QML memory cache for profile images, but that version regressed GIF loading on my NixOS setup, so I rolled it back for now.

The current branch keeps the stable behavior:

• GIF profile pictures use AnimatedImage, preserving animation.
• Static profile pictures continue to use the upstream CachingImage path.
• Global CachingImage behavior is unchanged.

I’ll keep the PR focused on the working GIF support first, and can revisit deeper integration with the new image utils/cache provider separately if needed.

Updated this PR after the upstream image cache provider changes.

The current version keeps GIF profile pictures on AnimatedImage, so animation is preserved and GIFs do not go through the static image cache provider. Static profile pictures still use the upstream CachingImage path.

Follow-up polish included:

• disabled QML memory cache only for profile images, so replacing ~/.face updates reliably;
• deferred dashboard profile image reload after picker accept;
• made image extension checks case-insensitive for .GIF, .PNG, .JPG, etc.

I intentionally avoided changing global CachingImage behavior and left MP4/WebM support out of scope for this PR.

Tested on my NixOS setup by rebuilding Caelestia Shell and selecting/replacing GIF profile pictures. Everything works as expected.

Rebased/merged onto the latest 2.0 changes, resolved conflicts, and re-tested GIF profile images. Also fixed the flake rev fallback so nix run github:TakuyaYagam1/shell/main works cleanly.
