Closes #23.

What changes

A Collect All button at the end of the Draw tab's Edit group pulls the boxes and strokes of ink that drifted apart on the open canvas back into a close group.

• Along each axis, every empty stretch of the page wider than a small gap (24 pt), including the margin before the first item, is closed down to that gap. Nothing else moves.
• Items keep their order across and down the page, and nothing ends up on anything it was not already on, because only empty bands are removed.
• Ink drawn over a box moves with that box, so annotations stay on their notes.
• One Undo puts the boxes and the ink back. The gathered layout is saved like any other box move.
• The view jumps to the page's top left afterwards, so the gathered page is in view.

Code

• crates/ui-egui/src/collect.rs: gather(items, gap), the geometry, with unit tests for far-apart items, small gaps, overlap safety, ordering and junk input.
• containers::Moved.frames: each box's frame in page points (normal and ink views).
• inkpad::Pad::stroke_bounds / move_each.
• docs/gaps.md describes the command under Pen and drawing.

Tests

• UI test collect_all_gathers_boxes_and_ink_that_drifted_apart puts two boxes at (40,20) and (3000,2500) and draws one stroke far down the page. It then runs Collect All and checks:
  • the first box only loses its margin, the far box comes back without overlapping the first, and the stroke comes closer;
  • the page file keeps the new layout;
  • one Undo restores both the boxes and the ink.
• The button sits after Format Background so the existing Draw-tab controls keep their places. An earlier placement pushed Format Background off the 1200 px test window.
• cargo xtask ci passes locally.
