chore(ci): refresh the Test Core shard-timings dataset (#21826)

Refreshes `scripts/test-shard-timings.json`, the balancing input for the
Test Core
shard split. Opened automatically by
`.github/workflows/shard-timings-refresh.yml`.
Every byte came out of `scripts/measure-test-shard-timings.mjs`; nothing
here was
hand-edited, and no bound, timeout or matrix entry was touched.

## Source

Measured across 1 accumulated run(s) of the HOURLY `schedule` run of CI
on
`main` — the full-battery run (#16467). A `push` run on `main` is
affected-only and
is not a measurement of the workspace, so no push run feeds this file.

No single green run measures the whole workspace either — turbo's cache
is namespaced
per shard and only main pushes write it, so a
package whose inputs have not changed is a HIT and the generator refuses
hits rather
than recording a replay as a duration. Runs are therefore accumulated,
each fenced by
its own `--run` group, until every package the committed dataset holds
is measured
again; a package seen in several of them gets the median of those
observations.

- https://github.com/objectstack-ai/objectstack/actions/runs/37262126122

- Newest run in the set: `37262126122`, commit
`75ddcd1b41e74823b7bb9f3fe9e159a189fa2a91` — the date this refresh
carries.
- Every run above had all six `Test Core (N/6)` jobs conclude `success`
with its six
run-summary artifacts still retained; runs that were cancelled, failed
or had lost
their artifacts were rejected by name in the log before any of these
were used.

All 72 package weights were measured in these runs; nothing was carried.

⚠️ This PR references #16173 and #16222 but does NOT carry a closing
keyword for them,
because a weekly lane cannot know which cards a given run ought to
retire. If this is
the first refresh to land, retire those two by hand as part of merging
it.

## Measured per-shard suite time on the newest run in the set

```
1: 759s  |  2: 2100s  |  3: 844s  |  4: 647s  |  5: 802s  |  6: 796s
```

## Predicted bins, before and after

```
BEFORE  partition-test-shards: self-test OK (72 measured packages -> 72 shard items, 6 shards, max/mean 1.12x <= 1.3x, floor 1391s, bins 1391/1208/1206/1208/1208/1208s, file-level slices: none)
AFTER   partition-test-shards: self-test OK (72 measured packages -> 72 shard items, 6 shards, max/mean 1.04x <= 1.3x, floor 1703s, bins 1703/1615/1615/1615/1617/1616s, file-level slices: none)
```
