Mechanical sweep of all .sx sources, plan docs, and tests/expected snapshots for the sx language rename (s8/s16/s32/s64 -> i8/i16/i32/i64). Verified: tools/run_tests.sh 23/23. Note: the ios-sim build has 2 pre-existing 'restart' dot-call errors from the sx opt-in UFCS change (sx a47ea14) — independent of this rename (present pre-sweep); migrated in the follow-up commit.
