Add Homey Community topic metadata

[jelledelaender]

Add the newly created Homey Community topic to the Homey app metadata.

Topic URL:
https://community.homey.app/t/app-soundtouch-bridge-local-presets-for-bose-soundtouch/156459

Expected metadata:

• homeyCommunityTopicId: 156459

Run the normal Homey compose/build validation so generated app.json stays in sync.

Implementation is ready for review in PR #32:

• PR: Add Homey community topic metadata #32
• Commit: 97596d4 (Add Homey community topic metadata codingmammoth/SoundTouchBridge#31)

What changed:

• Added homeyCommunityTopicId: 156459 to .homeycompose/app.json.
• Regenerated app.json so the Homey App Store metadata includes the community topic.

Verification performed:

• npx homey app build
• git diff --check
• npm test
• npx homey app validate

Homey build and validation passed; the CLI printed the known non-fatal local update-check warning for /Users/jelle/.config.
