A click with the loaded text cursor on a text frame inside a group showed the
not-allowed cursor and did nothing: `Document::hit_item` walks the spread's
top-level items, so the hit was the group, and the group is not a text frame.
`item_hit` already looks inside a group, but only to answer whether the group
was hit at all -- the frame in it was never named. InDesign threads into it.
`hit_descendant` names it: the frontmost descendant under a point that a
predicate accepts, through nested groups, front to back and skipping hidden
children. `ToolContext::hit_text_frame` asks for a text frame, and the thread
tool resolves its target through it, falling back to the plain hit so a click on
anything else means what it meant before. `hit` is untouched, so selection still
picks the group.
One fix covers the cursor and the click, since `click` resolves through
`target`. The test asserts the cursor, that the click threads to the frame and
not to the group, that `hit` still returns the group, and that a group holding
nothing threadable is still refused.
Add multi-click text selection, pending caret formatting and clipboard support, text-aware colour controls, guide/grid snapping, and frame threading with loaded-port interactions.
Include the layout, drop-cap and IDML updates carried from #83, with safeguards for generated and linked stories, external text references, local IDs, locked frames and atomic colour edits.
Fixes#23.
