Importing eval-store no longer spawns the gstack-slug subprocess: the
module-level DEFAULT_EVAL_DIR constant is now a memoized defaultEvalDir()
resolved at collector construction. Resolution order: explicit
constructor arg, then GSTACK_EVAL_DIR, then slug detection — so the
sharded paid runner can point each shard child at its own
<evalDir>/shards/<slug>/ dir with plain env, no --preload.
Runs collected under a shards/ subdir record their slug in the eval
JSON (EvalResult.shard). findPreviousRun scans one shards/<slug>/ level
and prefers same-slug priors, so each shard baselines against its own
history instead of whichever shard flushed last. eval:list,
eval:summary, and eval:compare enumerate the same one level of shard
subdirs; eval:compare's no-arg mode also stops picking an in-progress
accumulator as the after-run.
eval-watch stays flat (documented follow-up): it tails a single dir for
live progress and gains nothing from per-shard baselines until the
runner emits a merged stream.

isPartialEval(data, filename) is the one place that decides what counts
as an in-progress accumulator (the _partial flag OR a _partial-prefixed
filename), and findLatestFinalizedRun(evalDir, tier) is the one place
that finds the newest real run — scanning the eval dir plus one level of
shards/<slug>/ subdirs, where the sharded paid runner points each
shard's collector. skill-budget-regression.test.ts's hand-rolled
findLatestRun (flag-blind: a flagged-but-renamed accumulator passed its
name check) is replaced by the shared helper.

(cherry picked from commit b55fcf6966366fd21a8cdc46de61aab6e1b1d100)
findPreviousRun excluded only the file being written, by name, so every
suite compared against _partial-e2e.json — the current run's own
accumulator, relabelled with the current tier just before each flush.
That is why every block read '+$0.00, +0s, Stable run, no regressions.'
This harness has never been able to detect a regression, and reassuring
output that cannot fail is worse than none. In-progress runs are now
excluded by role, and a run with nothing to compare against says NO
BASELINE instead of claiming stability.

* feat: browser ref staleness detection via async count() validation
resolveRef() now checks element count to detect stale refs after page
mutations (e.g. SPA navigation). RefEntry stores role+name metadata
for better diagnostics. 3 new snapshot tests for staleness detection.

* feat: qa-only skill, qa fix loop, plan-to-QA artifact flow
Add /qa-only (report-only, Edit tool blocked), restructure /qa with
find-fix-verify cycle, add {{QA_METHODOLOGY}} DRY placeholder for
shared methodology. /plan-eng-review now writes test-plan artifacts
to ~/.gstack/projects/<slug>/ for QA consumption.

* feat: eval efficiency metrics — turns, duration, commentary across all surfaces
Add generateCommentary() for natural-language delta interpretation,
per-test turns/duration in comparison and summary output, judgePassed
unit tests, 3 new E2E tests (qa-only, qa fix loop, plan artifact).

EvalCollector accumulates test results during eval runs, writes JSON to
~/.gstack-dev/evals/{version}-{branch}-{tier}-{timestamp}.json, prints
a summary table, and automatically compares against the previous run.
- EvalCollector class with addTest() / finalize() / summary table
- findPreviousRun() prefers same branch, falls back to any branch
- compareEvalResults() matches tests by name, detects improved/regressed
- extractToolSummary() counts tool types from transcript events
- formatComparison() renders delta table with per-test + aggregate diffs
- Wire into skill-e2e.test.ts (recordE2E helper) and skill-llm-eval.test.ts
- 19 unit tests for collector + comparison functions
- schema_version: 1 for forward compatibility
