Emaki v0.2.3

• The sidebar lists every project and scrolls; pinned projects stay put above the rest, up to half the list.
• Projects in the sidebar are selected together with ⌘-click, ⇧-click, a dragged rectangle or ⌘A, then opened in Finder or hidden. Hidden projects and ones run in temporary folders sit under their own headings at the foot.
• All Projects is now All Sessions, with a scroll for its icon: projects unfold in place, each row shows its date, and archived projects have their own section.
• Sessions can be selected there, by project or one by one, and archived now or deleted. Archive checks Emaki's copy first; Delete moves every copy to the Trash. Nothing in a project's folder is touched.
• An agent's progress notes show as part of the reply, as in the terminal, and a running command says what it is for.
• Code blocks no longer wrap: a wide one scrolls sideways.
• A session begun by /clear opens with /clear, and no longer flashes under a stray folder in the sidebar.
• "New messages" scrolls down to the new part, and a project opened near the foot of a list scrolls into view.
• Fixes: stray lines around the logo in About.
