Ancilo 0.4.3

• Two people, one Mac: when someone else on the Mac runs Ancilo too, Ancilo no longer fails to start – it takes the next free port (the other one's stays untouched), and never mistakes the other person's Ancilo for its own.
• No silent quitting: if Ancilo's background service cannot start, the app says why (in the Mac's language) instead of disappearing.
• Tables that open right in Excel: a CSV a task writes is checked before it is saved – amounts like 312,50 between comma-separated columns used to split into two columns. The model is told how to write it right (quotes, or ';' between the columns). Found on a MacBook Air with Qwen3.5 4B; now 3 of 3 runs give a correct table.
• Run from the download? Opened straight from the disk image, Ancilo asks to be dragged into Applications first – otherwise its background service would point at a place that is gone after ejecting.
