feat(evals): sharded paid tier runner

scripts/test-paid-shards.ts runs the gate/periodic tier one Bun process
per test file, with an EXTERNAL wall-clock timeout that SIGKILLs the
shard's detached process group and an aggregate that distinguishes
passed / failed / timed-out / never-started — partial execution can no
longer read as a pass. Bun's native --shard/--isolate covers none of
this: no process-group kill (hung claude/codex PTY grandchildren
survive in-process isolation), no never-started taxonomy, no per-shard
env. Each shard child gets GSTACK_EVAL_DIR=<evalDir>/shards/<slug>/
(slug = test filename sans extension, stable across runs) so shard
baselines compare against their own prior runs.

Output classification lives in scripts/test-strict-output.ts (strict
exit-code derivation, incremental fail-line classifier, child signal
forwarding) so the runner and any future strict bun-test wrapper share
one implementation. Enumeration derives from the shared paid-test-set
module; tier exclusion fires only on an explicit whole-file
EVALS_TIER === '<other>' guard.

package.json gains test:gate:sharded / test:periodic:sharded, and
eval:bg:gate / eval:bg:periodic now run the sharded scripts with detach
timeouts sized to the worst case (gate: 49 shards x 30min / 4 jobs ~
6.2h -> 25200s; periodic: 59 -> 28800s).

test/paid-shards.test.ts pins enumeration, tier classification, and the
kill-and-continue property with a real busy-loop shard.
