v0.6.0

This release is mostly about the two screens you spend the most time in —
the graph and the assistant panel — plus a public place to see what's next
and say something about it without leaving the app.

Added

• Hierarchy collapse on the graph. Entities with children (a faction and
  its members, a town and its places) get a collapse/expand chevron on the
  graph canvas, using the same containment rules as the Entities list.
  Collapsing a branch hides its descendants and shows how many are folded
  away; "collapse all" / "expand all" live in the graph's overflow menu, and
  the collapsed state is remembered per project.
• Graph toolbar consolidation. Zoom, fit, reset and lock are one toolbar
  instead of scattered controls, with an optional grid and snap-to-grid for
  laying out a scene by hand. Edges declutter automatically based on zoom,
  hover and selection instead of staying uniformly dense at every level.
• One assistant composer. The input bar, attachments and send controls
  are a single component instead of three kept in sync by hand. The idle
  state and event notices read apart more easily, and the session-history
  menu now follows the app's own theme instead of default browser chrome.
• Modal project creation. "New project" opens as a dialog instead of an
  inline form on the projects page, which also gained filtering and a real
  empty state.
• Entity editor sections. The edit form is split into jump-to sections
  with delete moved into its own danger zone, instead of one long scroll.
  Creating an entity now stages its icon and shows the card preview before
  the first save. The rich-text toolbar tucks rarely-used actions into an
  overflow menu, and image cropping gained a Fit mode that pads instead of
  cropping.
• Project Hub & feedback, in-app. Help has a new support block linking
  to the public Loregraph Project Hub (roadmap, what's next) and a feedback
  form — both public Notion pages, opened in an overlay inside Loregraph via
  Notion's dedicated embed route rather than just a link out. "Open in a new
  tab" stays available in every state, in case an embed doesn't load. A
  compact feedback button also sits in the sidebar footer, since it doesn't
  need a project open the way Help does. No backend involvement — these are
  public URLs, nothing is proxied, and nothing is stored.

Changed

• Project settings' scrollbar gutter is now always reserved, so opening a
  panel that adds a scrollbar no longer narrows the page by a few pixels.
• The demo build's fake backend returns independent clones of its seed data
  instead of shared references, so editing one demo entity can no longer
  bleed into another.
• The image crop modal's Fit-mode backdrop is a blurred version of the image
  instead of a flat matte color.
