* test(#4784): failing-first — Xcode gates must pass -project and derive the destination from available simulators
* fix(#4784): Xcode gates pass -project '$XCODEPROJ' and resolve the destination from available simulators, skipping loudly when none exist
Also surfaces the -collect-test-diagnostics never / workflow.test_gate_timeout
guidance on a 124 timeout (a real iOS suite measured ~600s of sysdiagnose
collection after the tests passed).
* test(#4784): reachability-honest test shapes — apostrophe-confused prose (the path the false positive actually reaches past the splitter) and the file's single-quote convention
* fix(#4784): review fold-ins — unanchor the simulator extraction (real simctl lines end in a state suffix), escape apostrophes for the bash -c layer, assign the command variables on the skip path, behavioral extraction test
The isolated reviewer's Finding 1 was critical: the first cut's $-anchored sed
matched ZERO real simctl lines (every device line ends in (Shutdown)/(Booted)),
so the gates would have skipped on every machine. The 46,454-test green could
not see it (content assertions do not execute the pipeline); the new behavioral
test runs the gate's own extraction against a real-format line.
* chore(#4784): backfill changeset PR number (4879)
