Obsidian frame capture, sharper new-video detection, and steadier note viewing

📸 Obsidian frame capture

• Capture a scene into your note — the official Obsidian plugin (v0.2.0) lets you capture a frame from the video straight into your note. Whiteboards, diagrams, app screens — the moments that are hard to put into words go in as-is.
• Saved to your vault only — captured images are stored only in your vault. We never upload them to our servers. (Auto-updates from Settings → Community plugins.)

🔍 Sharper new-video detection

• Catches the videos it used to miss — fixed a case where channels posting several videos a day could let older ones slip past the detection window. Detection now catches all of them.
• Clearer registration copy + badges — channel registration now states the auto-analysis window accurately, and past videos outside that window get an "analyze manually" badge.

🩹 Note viewing & chapters restored

• Dashboard "View note" fixed — "View note" on the dashboard now opens the note detail directly instead of the list.
• Email note links restored — fixed email "View note" links failing with "invalid ID." Email, Obsidian, and PDF links all work again.
• Chapters restored — fixed a root cause where some recent notes were missing their chapter timestamps.

⚖️ Billing & delivery consistency + re-analysis

• No charge for empty manual runs — manual analyses no longer count against your quota when a note isn't produced.
• No duplicate digests — closed a rare case where the same digest went out twice.
• Re-analyze + low-cost regenerate — added a re-analyze button on partially completed notes, plus a low-cost option that reuses the existing analysis to rebuild just the note.

🔒 Security

• Tighter access control — re-locked an internal processing-status function to service-only access (migration 050).
