sync: multiple features from private repo

- quick-add-loading: fire-and-forget with loading placeholders, auto-open feed, SSE events, QuickAddInput redesign
- database-table-pane: TablePane + DatabaseTableView, countNodes(), event_date sort
- ui-polish-fixes: focus tab order, dim name editing, tab title sync, cost chip removal, custom sort drag-reorder, refresh button, dimension filter removal (~2,200 lines)
- node-creation-quality: description service prompt rewrite, title sanitization, extraction tool AI prompt rewrites
- feed-pane-ux: stripped kanban/grid/saved views, sort dropdown, AND dimension filtering, description preview

-GOAL: Include "who created it" when possible.
+Say WHAT this literally is and WHY it matters. Be concrete and specific — like you're telling a friend what this thing is in one breath.
 
-RULES (in priority order):
-1) ONLY use a creator if you have a creator hint (Author/Channel) or the content explicitly says "by <X>" / "hosted by <X>".
-   - Do NOT treat prominent people in the title/transcript (e.g. a guest) as the creator.
-   - If a creator hint is provided, prefer it.
-2) If you can identify a creator/author/channel/person/org from a creator hint, start with: "By <creator> — ..."
-3) If it's likely user-authored, start with: "Your <thing> — ..." (don't invent a creator name).
-4) If creator is unknown, do NOT guess; omit the byline.
+RULES:
+1) Name the format: "Podcast episode where…", "Blog post arguing…", "Your note on…", "Research paper showing…", "Idea that…"
+2) Name people by role — channel/host is the creator, title figures are guests/subjects. Use the Creator hint if available.
+3) State the actual claim, finding, or insight from the content — not a vague summary of the topic.
+4) End with why it's interesting or important — one concrete phrase.
+5) ABSOLUTELY FORBIDDEN — these words will be rejected: "discusses", "explores", "examines", "talks about", "is about", "delves into", "emphasizing the need for". State things directly instead.
 
-Then, in the remainder, state what it is (video/paper/article/note/idea/etc) + what it's about (high-signal).
-If unsure, say so briefly.
+GOOD: "Karpathy blog post — AI agents make software fluid, ripping functionality from repos instead of taking dependencies. Signals the end of monolithic libraries."
+GOOD: "Dwarkesh Patel interview with Anthropic CEO Dario Amodei — argues we're nearing the end of exponential AI scaling. Key signal for what comes next."
+GOOD: "Your note — morning optimism consistently reverses to evening pessimism. Not energy — the belief itself flips. Pattern worth tracking."
+BAD: "By Dario Amodei — discusses reaching the limits of exponential growth in AI, emphasizing the need for a critical perspective on future advancements."
+BAD: "This article explores ideas about how software is changing."
+
+Return ONLY the description text. Nothing else.
