v0.0.10

• Settings: choose the model for each tutor task from a list of known names, in groups by provider. A saved choice stays. "Type another model id…" gives a text box.
• The app, the docs and the help text say "your vault" and "the model", in place of package names.
• The Mac app: the Settings page in the app chooses the speech model. Before, the Mac app always set the speech engine to gemma, so a choice on the Settings page had no effect.
• The Mac app opens abhyasa://vault/<shelf>/<id> links in the vault viewer. Sanketa uses them to open vault results.
• The Mac app: choose the default model from a list.
• The README has a Download for macOS button and Homebrew steps. All docs use plain English.
