ara 0.1.2

[0.1.2] - 2026-07-11

Added

• Viewer: Tree display mode — an alternate DOM indented tree-list rendering
  of the exploration graph, reproducing the published research-visualizer
  scaffold. Chosen with a graph | tree segmented toggle in the header (the
  SVG graph stays the default). Rows show a kind glyph, node id, ⇠ id
  dependency marker, and title; children nest with a spine; dead ends are struck
  through; isolated-subtree roots render in an .isobox; hovering a row
  highlights its dependencies. Drives the same selection + filter as the graph.
  (#7)
• Viewer: Replay stepper in the toolbar (‹ / ▶ Replay⇄⏸ Pause / ›, ←/→
  keys) that steps the selection through node order in both display modes, with
  a shared step i / N · shown / N steps readout. 1300 ms auto-play stops at
  the last node; the ←/→ keys are guarded so they don't hijack the search
  field. (#7)
• Core: Node.isolated boolean manifest field (serde-default false, omitted
  from the wire form when false) marking the root of an isolated subtree; drives
  the tree mode's isolated-subtree box. Old manifests round-trip unchanged. (#7)

Changed

• Viewer: node kind glyphs now use the published research-visualizer set —
  experiment ✦, decision →, dead_end ✗, insight !, other • (question
  stays Q) — read from the single kind_meta source by both the SVG graph and
  the new tree-list. This visibly restyles the existing SVG graph's node glyphs.
