* test(performance): add J4 search journey
Measures typing a six-character query into the header search box on
/workspace/search until the global search results settle, on a profile
with the M3U fixture and the mock's existing 12,000-item `large` Xtream
catalog. Counters: bridge calls and SQL statements per search (with a
per-keystroke breakdown), serial IPC depth, DOM mutations, change-detection
ticks, layout shift and long tasks; wall-clock last keystroke to settled
and first keystroke to first result.
Runs in the existing journeys target and the warn-only CI job, whose
summary now prints the per-keystroke table. Moves J3's picsum artwork
blocker into a shared helper.

* test(performance): J4 settles only on the final term's query
The probe could settle on cards of an earlier term that stay visible while
the final term debounces. The journey now stamps every dbGlobalSearch trace
event in the main process, and the record requires the last query between
the sentinels to be for the final term and to have completed before the
end sentinel. Iterations with a keydown gap over 250 ms (below the 350 ms
debounce) are rejected; gaps and the final query are kept as evidence.

* test(performance): anchor J4's SQL count to the journey sentinels
renderer.sqlStatementsPerSearch was the difference of test-side samples
taken before the first key and after the end sentinel had been read, so
database work in either gap could be counted. The main process now reads
main.sqlStatements when the start and end sentinels arrive, and the counter
is their difference; sqlStatementsAfterSettled starts at the end sentinel.

* test(perf): measure the serial IPC depth before the J1 first card
Adds renderer.ipcSerialDepthToFirstCard to the launch journey: the length
of the longest chain of bridge calls in which each call started after the
previous one completed, among calls that completed before the first card.
The main IPC capture now records the ordered start/completion timeline;
the depth, its lower bound, the chain and the timeline are per-iteration
evidence, and the CI job summary prints the chain.

* test(perf): keep the IPC timeline consistent around the J2 start marker
A call that started before the start marker no longer records its
completion in the timeline, and completions of a method with calls in
flight both inside and outside the timeline are attributed outside and
counted, instead of skipping the first marker-method completion.
