convert to headless puppeteer

[cameronaaron]

Summary:
This pull request replaces Electron with Puppeteer for headless browser automation in the Matrix-Google Voice bridge. The key motivation for this change is to reduce resource usage and simplify deployment, especially in containerized environments.

Key Changes:
Browser Initialization:

Replaced Electron-based initialization with Puppeteer.
Puppeteer now handles launching a headless browser to interact with Google Voice.

Script Injection:

Script loading previously done via webContents in Electron is now handled with page.addScriptTag() in Puppeteer.

Request Interception:

Network request interception logic has been moved to Puppeteer’s page.on('request', ...) to block unnecessary requests and allow only essential ones.

JavaScript Execution:

Replaced Electron’s webContents.executeJavaScript() with Puppeteer’s page.evaluate() to execute custom scripts within the browser context.

Inter-Process Communication (IPC):

Retained the same IPC mechanism (stdin and stdout) for communication between the Go application and the headless browser, ensuring backward compatibility.
File Renaming:

Benefits:
Reduced Overhead: Puppeteer is lighter than Electron, leading to lower resource usage.
Easier Containerization: Puppeteer integrates better with containers, eliminating the need for Electron’s GUI components.
More Streamlined Dependencies: Fewer dependencies are required compared to Electron.
Testing:
Successfully tested all major functionalities, including:
Browser initialization
Script injection
Request interception
JavaScript execution
IPC communication

@cameronaaron Should this PR work? I am trying to run it with a customized dockerfile chaoticbear#2, that should run puppeteer and puppeteer installed globally, but getting an error: Error: Cannot find module 'puppeteer'

I have it installed and running, thanks for this branch!

However, I'm seeing the same issue as #4 -- I can receive messages just fine, and if I send messages from the web interface it shows up in my matrix chat windows, but anytime I try to send from matrix, I get error 429. Any thoughts?

oh I forgot I started this i'm surprised it even works that much :/ I will look at this tomorrow and finish it up

For what it's worth, I see that I've made two slight changes, presumably because it didn't work otherwise? I don't exactly remember what happened, or whether it's specific to this branch vs main, but this is the current state of my repo:

• gvoice/Dockerfile

  Line 7 in 46efc06

  RUN go build -o /usr/bin/mautrix-gvoice

  • RUN sh build.sh -o /usr/bin/mautrix-gvoice

• gvoice/build.sh

  Line 4 in 46efc06

  go build -ldflags="-s -w $GO_LDFLAGS" ./cmd/mautrix-gvoice "$@"

  • go build -ldflags="-s -w $GO_LDFLAGS" "$@" ./cmd/mautrix-gvoice

I've never used go, so I don't know if this is actually necessary to get the docker to build, or if this is just me somehow being silly.
