Steady watch playback was repeatedly rebuilding the player layout and queue while running continuous decorative animations. This ports the same performance fix tested in LMusic f0b7c94.

• Separate position updates from the main player display state, draw progress once per second using cached paths, and avoid rebuilding the queue on position ticks.
• Suspend UI polling in ambient/background mode and load hidden pager/artwork pages on demand.
• Keep the play star and EQ indicators stationary during playback, retaining brief play/pause transitions.
• Preserve Nobody Listens' Daylight design, fonts, playback features, audio quality, streaming buffering and Wi-Fi handling.
• Bump the patch version from 1.5.0 to 1.5.1 (local version code 2) and add the release notes used by the main-branch publishing workflow. CI continues assigning its increasing release version code.

Validation: :wear:testDebugUnitTest passes all 16 tests; :wear:assembleDebug succeeds; changed-source whitespace and the repository's 700-line Kotlin limit pass. Paired-phone and signed-in account tests are outside the current emulator-only scope.
