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.

Regression readings: NOT MEASURED -- the diff refused (exit 1)

What the seat landing this PR does

File nothing from this refresh's readings: no rise and no file was judged. The refusal above
is a defect in this lane, and that is the one card to file.

Source

Measured across 7 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: 39202368342, commit 725a5b1311ecc051edafcd8122ad47dfe1ccfbf8 — 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 75 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 75 weights rests on at least 3 executed runs; none is provisional.

Suite-duration ceilings: 72 held unchanged (a refresh never moves one; a raise is a ruling), 3 new (@objectstack/connector-imap, @objectstack/service-mailbox, @objectstack/service-print), each new one its slowest executed run in this window x 1.25.

Every package carries a ceiling.

⚠️ 17 package(s) ran OVER their held ceiling in this window (marked in the table): a reading, not a red -- under #22949 ruling E the ceiling reports on every event, and a regression is judged by the diff at the top of this body. This refresh does not raise them; that takes a ruling.

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.
