- Action buttons overlay: wrap pin/move/archive/dup/trash in a
.session-actions container with position:absolute. Titles now use
full available width. Actions appear on hover with gradient fade
from the right edge. Overlay auto-hides during inline rename.
- SVG line icons: replace all emoji HTML entities with monochrome
SVGs that inherit currentColor. Consistent across all platforms.
- Pin indicator: small gold star rendered inline only when pinned.
Unpinned sessions get full title width (zero space reservation).
- Project border: sessions assigned to a project show a colored
left border matching the project color, replacing the old
always-visible blue folder button.
Fixes both BUGS.md items (title truncation + sticky folder button).
Tests: 214 passed, 23 pre-existing failures, 0 regressions.
