Add oma-preview: native PDF reader/editor with visible agent review - #305

Summary

Add oma-preview 0.10.0, a Rust/Quickshell PDF reader and editor built for Omarchy. I maintain the upstream project.

Continuous reading, highlighted search, bookmarks, text overlays on non-fillable PDFs, reusable handwritten signatures and page assembly. Private drafts preserve edits and up to 100 undo/redo changes across reopening. The JSON CLI lets agents propose visible changes in the running window; users can correct them before exporting a separate PDF.

0.10.0 adds edge-revealed controls and scrollbars, sharper scrolling, retained-frame single-page reading, faster mouse-wheel page turns, Ctrl+wheel zoom, and confirmed draft clearing. Restored-draft notices stay below the drawer and dismiss automatically. Existing mouse-wheel precision and trackpad momentum remain covered by regression tests.

Packaging

• Local-source PKGBUILD, pinned v0.10.0 tag and SHA-256; no AUR account required.
• Normal edge-first policy, no fast-ring override or automatic upstream sync.
• Installs the binary, QML UI, native hold-gesture module, desktop file, icon, license and optional agent skill under /usr.
• Qt 6.11+ runtime; CMake, pkgconf and wayland-protocols build dependencies.
• Native hold gestures use Qt’s existing Wayland connection; no raw device permissions or compositor configuration changes.
• Does not change default applications or write into home directories. Existing Folio private-storage paths are retained for compatibility.

Validation

• x86-64 makepkg build from the published tag, including source checksum verification and 13 Rust/CLI tests.
• Local isolated UI checks cover native wheel/trackpad input, search, draft clearing and failure recovery, annotations, reader lifecycle, page identity, controls and a 2,048-page synthetic fixture.
• Retained-frame checks on a 12-slide presentation captured no blank transition frames at 1× or 2×; the source remained unchanged.
• All 29 isolated UI checks pass against the extracted x86-64 release package.
• Clean Arch build and full suite passed.
• Fresh installation of the public package passed, including installed-file integrity/version and all 29 installed-UI regressions.
• Release checks and methodology.
• ARM64 source builds are declared but remain untested; maintainer build validation is needed. Automated captures are not physical-input or low-end-hardware benchmarks.

This does not request changing the default PDF app. I can maintain package updates through follow-up PRs.

Screenshots and demo

Freshly captured from the actual 0.10.0 app: reading, edge controls, Find, bookmarking, typing, resizing, correction, undo, three palettes, export and clearing a draft.
