bflatasticandClaude Opus 5.5 2925e7f9b5 M4.63: Links panel with status, Relink, Go To, Update, Edit Original, Embed/Unembed, Link Info and Placement Options
The Links panel lists every image (thumbnail, name, page, missing/modified/embedded
badge) with Show filters, sorting and thumbnail sizes; its buttons and flyout relink
(to a file or a folder), go to, update, edit the original, embed and unembed, show in
folder and open Placement Options. Link Info shows format, colour space, location, ppi
and effective ppi, dimensions, scale, rotation, size and dates. Edit > Edit Original
and the Properties panel's image section reach the same commands.

Engine: links.list, links.goTo, links.embed, links.unembed, links.info and
links.placementOptions; links.relink and links.update now place the new file as the
image's Placement Options say (transforms, bounds, file dimensions, fit, fill, the
alignment point, clip to the old bounds). Model: ImageObject.placement.
UI: links.editOriginal, links.reveal, ui.placementOptionsDialog; Services.open_file
and pick_folder on the desktop.

//! VectorCraft's egui frontend: an Illustrator-style UI over `vectorcraft-engine`.
//!
//! The UI is thin: every action goes through [`VectorcraftApp::run`], which dispatches UI commands
//! (view/window) here and everything else to the engine. The same entry point serves menus,
//! shortcuts, the ⌘K palette and the control channel ([`control`]).
