TestandClaude Fable 5 c49b2ece15 fix(test): per-shard CHROMIUM_PROFILE — the collision class duration packing exposed
Nine test files launch in-process persistent contexts or daemons that
default to the SHARED ~/.gstack/chromium-profile. Two concurrent shard
processes on one profile dir kill each other's browser — observed live
on CI once duration packing recomposed shards: handoff's
launchPersistentContext died 'Target page, context or browser has been
closed' (--user-data-dir=~/.gstack/chromium-profile in the call log)
while a sibling shard's daemon logged 'Chromium process crashed'. Hash
sharding had masked the collision by chance placement; handoff passes
standalone everywhere.

Fix at the runner, not per file: each shard child gets
CHROMIUM_PROFILE=<shard-state>/chromium-profile (the documented env
knob, same isolation idea as the existing per-shard TMPDIR). Files
within a shard run serially, so sharing the per-shard profile is safe;
config.test's resolution-order tests save/restore the env around their
assertions.
