add D-055 Claude internal tabs, readable session name slugs

Browse Source 
D-055: multiple Claude sessions share the workspace as internal
tabs inside the Claude pane header. Primary has no close; secondaries
show ×. Tab row hidden when only primary exists. + button and
double-click-empty spawn new secondaries.

Session names now use a readable path slug (strip $HOME, replace /
with -) with fallback to FNV-1a hash when the slug exceeds 80 chars.
