Improve the developer experience by providing structured setup scripts,
VS Code workspace configurations, and detailed documentation.
- Add VS Code workspace configuration and recommended settings
- Update README.md with system requirements and VS Code setup instructions
- Refactor `script/setup` to include Python 3.11+ validation and system dependency checks
- Add option to skip PulseAudio wait in `docker-entrypoint.sh` for local development
- Update `.gitignore` to ensure consistent version file handling
Use events and commands to control custom onboard leds and buttons. Can be used to communicate with an external Python script via a WebSocket API running in a container alongside LVA.
Add a configurable amount of delay (defaulting to 0.5s) after the TTS playback is finished to avoid the mic to capture the end of response during start/continue conversation.

## WebRTC Auto Gain & Noise Suppression
This PR adds support for WebRTC Auto Gain and Noise Suppression as previously implemented in the Wyoming Satellite project.
### What's New
Two new entities have been created a number slider for gain and another one for noise suppression. The processing happens inside of the `webrtc.py` file and is implemented in the `__main__.py` file's `process_audio` function. The slider for gain has a limit of 0-31 and noise suppression has a limit of 0-4.
The Auto Gain and Noise Suppression persist through restarts and are saved as preferences. The values are dynamically chnged without needing a restart.
CLI flags called `--mic-auto-gain` and `--mic-noise-suppression` have also been added.
> When both values are 0, WebRTC processing is bypassed entirely with no performance overhead.
Closes#25
### Testing
When saving the audio recorded by LVA there is a noticeable increase. The following two files have been recorded with similar audio being played through them with these results (Gain-31 and NS-4):
| Metric | With AGC+NS | Without |
|---|---|---|
| Max amplitude | 0.329 | 0.054 |
| RMS amplitude | 0.008905 | 0.002862 |
| Volume adjustment needed | 3.034x | 13.479x |
| Rough frequency | 916 Hz | 705 Hz |
Introduce a new `--output-only` command-line flag and corresponding `ENABLE_OUTPUT_ONLY` environment variable. This allows users to run the assistant in output-only mode, where it only supports announcements. The change includes updates to configuration examples, documentation, and the Docker entrypoint script.
Breaking Change: From now on the cookie file will be created in the configured directory/file. There will be no alternative directory where we try to create and touch the file. You need to make sure that the configured directory is writeable from the application.
* moved port check from shell script into the python application
* fixed pulseaudio check console output
* portcheck has now 15 chances to get the port before abort
* Change Client-Name: The client name inside LVA is not capable of having spaces in the name. Fixed the example.
* Add first version of Docker-Compose for developers
* Add variable for network-interface and auto detection by default
* Added autodetection for the MAC-Address based on the detected or specified network-interface.
* Switched from listening on all IP-Addresses to the IP of the default interface, usually u set the correct network-interface and it will automatically detect the right IP-Address.
* Added missing variables, fixed variables names
* Fixed not working variables for example sound-files.
* Moved the auto-name creation from shell to python. The name is no longer mandatory, it will be generated if no name is given.
