Atelier Studio 1.5.0

Atelier Studio 1.5.0

The conversation and evidence release. The chat surface is rebuilt around an
annotated margin that replaces the old pill rail and shows where you are in
the thread; reasoning now reads as prose instead of a raw block, every
touched file opens its own diff beneath its line, and every second of a turn
is accounted for with named targets, a live ticker, durations and timed
waits. A project now reopens exactly where you left it.

New Evidence surface: gbrain passages pinned per project and grouped by the
claim they support, with /ref as a deterministic trigger for reference
lookup. The PDF viewer gains four Zotero 7-style annotation tools and a
Library scope that gathers annotations across every article. The LaTeX
Reading view becomes full-frame, annotatable and editable in place, with
three backgrounds, a text-size control, and diff marks shown on demand —
deletions expand inline at their exact position.

Under the hood, the Rust port of the knowledge base (plan 065) becomes the
default engine.

Breaking change: the Node and Python gallery backends and the
ATELIER_GALLERY_BACKEND variable are gone — the gallery server is Rust only.
