Flowlight 0.9.0

What's new in 0.9.0

• A new screen: Coverage. Every other screen says what happened. This one says what you would not have been told — per app, and separately for each of the three ways it can go wrong. Was the connection seen at all: the filter sees flows as they open, while the sampler reads counters once a second and misses whole connections between readings. Was the destination named, measured in bytes rather than connections, because one unnamed connection carrying a gigabyte is a bigger hole than a hundred carrying a kilobyte. And was it readable — with being on the Never decrypted list counted as the choice it is, not as a failure.
• What no engine sees is on the screen, not in a footnote: traffic from before capture started, system services content filters are never shown, apps that pin their certificates, QUIC, and an agent's local MCP server talking over a pipe. A coverage figure that counted only what it could see would be a reassurance rather than a fact.
• A crash that was waiting for a tenth screen. The sidebar derived ⌘1 to ⌘9 from each item's position, so adding a tenth produced an impossible keyboard shortcut and trapped on launch. It runs ⌘1–⌘9 then ⌘0 now, the way browsers number tabs.
