Daniel Han fdf7f94f46 ci(mac): single-process Chromium + JSON.parse try/catch in pipeTransport
Run 25491698868 / job 74801076186 hit the Playwright pipeTransport
'Unexpected end of JSON input' crash on ALL THREE retry attempts
(at 11:00:52, 11:01:07, 11:01:21 — only ~15s apart). The retry-with-
Studio-reset wrapper from d35bf6a couldn't recover because the
crash hits 100% of attempts on this run, not as a rare race. Two
complementary fixes:

1. tests/studio/playwright_chat_ui.py + playwright_extra_ui.py:
   pass --single-process / --no-sandbox / --disable-dev-shm-usage /
   --disable-gpu to chromium.launch. --single-process is the key
   one: it keeps the renderer in the browser process, eliminating
   the browser↔renderer IPC pipe that was the actual crash site
   (Chromium's renderer was dying mid-startup and corrupting the
   pipe stream the Node driver was parsing).

2. .github/workflows/studio-mac-ui-smoke.yml: backport upstream
   Playwright's try/catch around the two JSON.parse(message) sites
   in driver/.../pipeTransport.js so a malformed stdout chunk
   (e.g. empty buffer between two \0 delimiters) is dropped
   silently instead of throwing and killing the entire Node driver.
   Newer Playwright versions ship this guard upstream; we patch it
   in via a python script after `playwright install chromium` so
   the fix lives only in CI's Mac job. Idempotent: prints "no
   matches; skipping" if upstream changes the pattern.

The retry loop from d35bf6a is kept as a third line of defense
for any residual Chromium-died-and-stayed-dead scenarios.
