v0.2.10 — Don't draw circle background by default

Changed

• Disabled faint_background_when_missing by default.
• The optional circular background can still be enabled manually for icons that look visually unbalanced after the fallback slash is applied.
• Updated the documentation to explain that Home Assistant uses the circle as an interaction cue: it normally indicates that clicking the icon performs a separate action from clicking the rest of the Tile card.

Fixed

• Fixed language links in HACS by replacing unsupported HTML word-joiner entities with native Unicode word joiners.
