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

[github-actions]

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 12 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 has been EXECUTED by at least the
generator's minimum number of them, and each weight is the median of those executions.

• Newest run in the set: 38195222269, commit eab7236ff70d2c4217706e932d14a64ca25e8d2e — 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.

Sample depth, run-to-run spread and suite-duration ceilings

Every one of the 72 weights rests on at least 3 executed runs; none is provisional.

⚠️ This refresh writes the FIRST suite-duration ceiling table: 72 package(s) get a ceiling, each its slowest executed run in this window x 1.25. From the merge of this PR the Test Core check (scripts/check-test-suite-ceilings.mjs) grades every executed package against it -- until then it reads NOT MEASURED. Every later refresh HOLDS these numbers and a ceiling rises only by a ruling, so review the ceiling column below before merging.

Every package carries a ceiling.

Each package's executed runs in this refresh (minimum 3), the spread of its readings in seconds, and the suite-duration ceiling Test Core grades it against: its slowest executed run x 1.25 when first set, then held by every refresh -- a ceiling is raised only by a ruling.
