Subject: [PATCH 1/2] ci: fix turbo cache path to .turbo/cache

The `actions/cache` step pointed at `node_modules/.cache/turbo`, which
is turbo v1's default. Turbo v2 writes to `.turbo/cache`, so the cache
path bound to an empty directory: the post-action save silently wrote
nothing, no `turbo-Linux-*` key ever landed in the pool, and every run
three-way-missed the restore keys (observed on PR #72 logs).

Net effect: seven tasks marked `cache miss, executing` on every PR
unit job, turning a YAML-only PR into a full 232s cold run.

Subject: [PATCH 2/2] ci: split turbo cache key per job to avoid save race

typecheck and unit jobs shared the exact same cache key
(turbo-Linux-<hash>-<sha>). With path now pointing at the real
turbo v2 cache dir, they would race on reserveCache: typecheck
finishes first (~60s) and wins the reservation, unit (~232s)
hits ReserveCacheError and skips upload.

Effect: pool accumulates only typecheck-flavored tarballs. Next
run's unit job restores typecheck's cache, finds no matching
test:ci task hash, and re-executes the full 232s suite.

Split the key with a job discriminator (-typecheck / -unit) so
each job saves and restores its own slice.
