Opticast 1.0.2

Fixed

• SRT publishing to MediaMTX. Connections now use the publish:<path> stream ID format MediaMTX expects; the previous publish/<path> form was rejected by the server. Thanks @tortillas5 (#1).

Opticast 1.0.1

Added

• Focus mode selector on the live screen: Auto (continuous autofocus), Lock (freeze focus at its current distance), and Infinity (lock focus at infinity for fixed mounts pointed at a far scene, so a near bright object can't steal focus). The chosen mode is persisted across sessions.
• Animated focus-square indicator on tap-to-focus.

Fixed

• Tap-to-focus no longer fires at the end of a pinch-zoom or a drag — only on a genuine single, stationary tap, so focus stops jumping to unintended spots.
