fix: batch tag queries, inline edit, delete response, SPA catch-all, link glyph

- Fix N+1 tag query in List() with batched IN clause
- Add inline body editing in web detail pane (dblclick or e key)
- Delete API returns {result: "soft"|"hard"} with 200 instead of 204
- SPA handler serves index.html for all extensionless paths
- Link glyph changed from emoji 🔗 to unicode ↗ for terminal alignment
- Capture bar contrast and hover glow increased
- Comment on load-bearing "--" in root.go
