chore: sync Obsidian UI changes

calendar/data.json — configured through Obsidian UI:
  - Word count dots: #ebcb8b, 250 words/dot, calendar + menu
  - Task dots: #d08770, max 1 incomplete, calendar + menu
  - Link indicators: #a3be8c, menu only
  - Backlink indicators: #5e81ac, menu only
  - Zettel tracking: #b48ead, calendar + menu

community-plugins.json — enabled through Obsidian (may include dataview etc)
workspace.json — updated open tabs/layout state
graph.json — Obsidian reset colors on close (expected behavior)
