linexcel 1.13.0

[1.13.0] — 2026-10-02

Added

• Build and save a whole-workbook graph hierarchy in a resource-isolated server
  task, independently of formula evaluation. Each browser view has at most 32
  groups/cells plus the rest of the workbook, with server-provided positions,
  weighted dependencies, internal counts, breadcrumbs and direct cell lookup.
  Retain cross-group links and grouped ranges without accumulating the entire
  graph in browser memory. Support cancellation, task recovery and cache
  invalidation after structural reimport.
• Separate import/graph time budgets (600 seconds by default) from targeted
  recalculation (120 seconds), and resolve exact cell searches through the SQLite
  node index instead of a workbook-wide substring scan.
• Add a persistent Manual recalculation (lazy) checkbox. By default, selecting
  a formula still requests its targeted calculation; manual mode only reads saved
  evidence until Recalculate is pressed. Neither mode recalculates the whole
  workbook or automatically requests AI documentation.

Changed

• Refresh the English application screenshots for the server-backed graph and
  manual recalculation controls.

Fixed

• Preserve the case of graph searches sent to the backend so exact cell references
  use the indexed lookup and exclude cells with longer, matching prefixes.
