v0.6.1
Mind maps of long meetings build in the background

Improved
- Wispra Cloud explains clearly when this month's AI allowance is used up: how much was used, when it resets and what you can do.
- Dictation keeps working when the allowance is used up: your words are typed as heard, without the AI cleanup.
- A chat question that could not be answered goes back into the box, so you can send it again later.
Fixed
- A mind map of a long recording could spin forever. It is now built in the background: it waits for the AI provider's limit, keeps every finished part, and continues after an error or after Wispra was closed. Keep working while it runs.
- The tab shows real progress ("5 of 9 parts done"), and a small mark in the recording list shows whether a map is being built, ready or unfinished.
