/**
|
|
* gstack browse server — persistent Chromium daemon
|
|
*
|
|
* Architecture:
|
|
* Bun.serve HTTP on localhost → routes commands to Playwright
|
|
* Console/network/dialog buffers: CircularBuffer in-memory + async disk flush
|
|
* Chromium crash → server EXITS with clear error (CLI auto-restarts)
|
|
* Auto-shutdown after BROWSE_IDLE_TIMEOUT (default 30 min)
|
|
*
|
|
* State:
|
|
* State file: <project-root>/.gstack/browse.json (set via BROWSE_STATE_FILE env)
|
|
* Log files: <project-root>/.gstack/browse-{console,network,dialog}.log
|
|
* Port: random 10000-60000 (or BROWSE_PORT env for debug override)
