The wine blocking job flaked with ERR_PNPM_ENOENT rename '_tmp_*' ->
'<pkg>/node_modules/esbuild' during workspace snapshot + pnpm install
(runs 30334004123 and 30340039598), and a plain rerun passed. Root
cause is upstream pnpm/pnpm#12880: the hoisted linker's parallel
linkers race to rename their _tmp_* staging directory onto the same
nested package path, and the loser exits although an identical
re-install succeeds. Only this lane uses nodeLinker: hoisted, so only
this lane hits it.
snapshot_and_install now retries exactly that log signature up to two
times, wiping the scratch tree's node_modules first (the snapshot
itself contains none, so the wipe restores the pre-install state) and
logging each retry with the upstream issue. Any other install failure
still fails on the first attempt, and a race that survives the final
attempt still fails loud with the install log tail.
