A browser that died between two tests left the next one only 'Target page, context or browser has been closed': Playwright logs a browser's stderr and exit only on the pw:browser debug channel, which CI leaves off. Each worker now keeps that channel as a bounded tail, prints one pm-browser-exit| line on an abnormal exit and attaches the tail as browser-stderr.txt to a test that fails on a closed or crashed target. Nothing is retried or hidden. Refs #513

// Shared `test` for the page workflows: every Playwright worker owns one
|
|
// tests/browser/server.py process on a port the OS chose for it, with its own temp root
|
|
// and database. `baseURL` (and so `page`, `request` and `browser.newContext`)
|
|
// points at that worker's server. A server that dies fails the running test
|
|
// with its stderr tail, and the next test in the worker gets a fresh server.
|
|
// A test that fails gets the stderr its server wrote during it attached as
|
|
// `server-stderr`. The worker also records its browser's own log (#513): a
|
|
// browser that exits abnormally prints one `pm-browser-exit|` line, and a test
|
|
// that fails on a closed or crashed target gets that log attached as
|
|
// `browser-stderr`.
