Decor Sounds 0.7.11 beta

- Add background sounds and sound zones outside your house, within your housing lot.
- Outdoor settings are separate from indoor rooms and backgrounds.
- Outdoor zones use the existing radius, layer/replace, loop/once, mute and time-of-day controls.
- Background and zone panels show outdoor labels while on a plot.
- Plot boundaries stop playback; your setup does not follow you into neighbouring plots.
- Wait for fresh plot information on entry. Ignore retained house information on the street.
- Identify outdoor settings by neighborhood and plot number, independently of session-local house IDs.
- Saved builds and recovery drafts retain indoor and outdoor settings together.
- Share an outdoor setup while on the plot; interior and exterior exports are separate.
- Installed visitor packs apply only to their matching plot, with visitor playback enabled.
- Outdoor zones use horizontal distance. Height detection is not yet verified outdoors.
- Existing indoor settings, custom sound registration and the player's Music preference are preserved.

Validation: full addon Lua 5.1 load and mocked UI/playback tests, including metadata gaps,
stale identities on streets, neighbours, world transitions, build restore and exports.
Outdoor playback itself still needs a test in the live game.
