[Feature]: HTTP proxy support

[emocharnik]

1. Is your feature request related to a problem? Please describe.

Currently, the extension does not support HTTP proxies, which can be a challenge for users working in environments where internet access is restricted or managed through a proxy. This limitation hinders connectivity and functionality for users behind corporate firewalls.

2. Describe the solution you'd like.

Implement HTTP proxy support within the extension, allowing users to configure proxy settings via the extension's configuration options or automatically inherit system proxy settings. This would ensure that the extension can function properly in environments requiring proxy access.

3. Describe alternatives you've considered.

• Manually configuring proxy settings outside the extension, such as through system-level settings or environment variables, but this is not always effective or user-friendly.
• Using a different extension that has built-in proxy support, though this may lack the specific features of this extension.

4. Additional context.

Including proxy support would improve accessibility and expand the potential user base for the extension, especially in corporate or restricted environments.
