Switches the controller from pql.outlinks to pql.meta (outlinks + tags in one call per file) and strips #heading fragments from link targets, so a heading link now connects the two notes. Adds a filter bar above the graph: a path glob that re-queries pql on submit, a depth-from-active selector for the local graph around the open note, and tri-state tag pills (neutral / include / exclude). The pane draws the filtered visibleGraph. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
